Mineral deposit prediction method

FIELD: geology, particularly to predict aerial extent and localization of metal, non-metal and fuel deposits of any genesis and age.

SUBSTANCE: method involves discovering geological structures and determining perspective zones for further deposit prospecting. In the case of ore deposit prediction above perspective zones are determined in low-order dome and composite type structures allied with crystal magma chambers and located over faults of different orders or in areas in which faults of one or several classes intersect. In the case of gravel deposit prediction the zones are determined in area located near ore deposits in neighboring low-order depression structures. In the case of oil and gas reservoir prediction the zones are prospected in all medium-order structures along radial, ring or oval fault areas and along super-deep ring or oval fault areas in zones in which crystal magma chambers are absent.

The invention relates to Geology and can be used for large-scale forecast areal distribution and localization of deposits of different Genesis and age of metal, non-metal and fossil fuels on Earth.

Known methods of mineral exploration is based on geological mineralogical mapping, geochemical sampling, measurements of gravity field, magnetization, conductivity, speed of propagation, etc. When this is geological survey of the territories on a pre-planned network, selected mineralogical and geochemical samples from indigenous and alluvial sediments, measured by various devices. Subsequent processing of the data allows us to delineate the areas with the presence of those characteristics that are recognized as informative in the study samples. The end result of searches are areas of bodies composed of diamond-bearing rocks (see the Main provisions of the organization and production of geological and mineragenic mapping scale of 1:200000. - The Ministry of Geology of the USSR, GIP regional study of the geological structure of the country. - Moscow, 1986).

The disadvantages of this method are the high complexity and duration of the search process, as well as low reliability of the results obtained through nevozmozhno and testing sufficient indigenous sources.

Closest to the claimed method is the search for mineral resources, including the interpretation of space images for the detection of geological structures, including linear, circular and curved elements of the landscape, in this case, initially allocate areas for extended hundreds of kilometers bundles of unidirectional lanamento, followed by ring-like structures with a diameter of up to 250 km and emit zonal manifest annular education diameter 170-200 km, namely zonal circle with a core diameter of 50-70 km and the surrounding areas with a width of 30-60 and 50-70 km, and diamondiferous kimberlites and lamproites are confined to the nuclei of the above structures or located in the border zones between the core and the average area, and a middle area and an external area, in the areas of their intersection with a radial structures (see p. RU # 2069379, IPC6G 01 V 9/00).

This solution can be used to search only diamonds and only on the area of landscape elements (platforms) with different zones for extended hundreds of km wide and tens of km) bundles of unidirectional lanamento, followed by ring-like structures with diameters of up to 250 km

The technical result of the claimed technical solution is the provision of large-scale forecast areal distribution and localization of the various fields is on the Genesis and age of metal, non-metallic and fossil fuels.

The technical result is achieved in that the method of prediction of mineral deposits involves the identification of geological structures by defining them in promising areas of the search fields, while secrete large geological, planetary order, platformbased structure with an average diameter of up to 15,000 km, and their boundaries sverhnegativny - the nuclears - 9000-3000 km, megastructures high order - 1500-1000 km and dome, depression and mixed-type structure in the middle order - 600-300 km and structure of small order - 40-5 km, and there are separate sverhnegativny - the nuclears and megastructures with the corresponding structures of the lower order, with all geological structure formed adjacent parallel zones of faults: transform - to platformbased, in-depth - for zwerglgarten - nuclears and mega-structures of high order, depth - to medium-range order structures and core - structures of small order, circular or oval ring network and the radial faults with this transfer, in-depth, in-depth and crustal faults have the same ranking for each structure and are located toward the center of the structures with a pitch of 1200 km and less for platformbased, 600-300 km for vermagest the tour the nuclears, 400-200 km for mega-structures of high order, 20-8 km for medium-range order structures and 2-1 km for structures of small order, and promising area forecast for ore deposits determine the structures of the dome and mixed type of small order, genetically connected with the core magmatic centers and located above the fault of a different order or at the intersection of the same or different grade of faults, for placer deposits in the area around ore deposits in the adjacent depression structures of small order, and for oil and gas in all the structures of the middle order along zones transform radial, circular or oval ring faults and along zones superdeep oval-ring and ring faults in the part where there is no crustal magma sources.

To identify geological structures to determine them in promising areas of the search for deposits of different Genesis and age of metal, non-metal and fossil fuels by the author for the first time is considered a great geological continuum with generalized positions real independent natural process of self-organization of matter in the form shells around certain centers, the primordial basis of which in the microcosm is the atomic structure of the core and shell around it orbits of electr is new. Such centers for geological platformbased ring structures, the diameter and the radius which exceeds the radius of the Earth (6371 km), is the heterogeneity in the structure of its nucleus, where regular softening and moving melts of mantle material laterally and vertically. The surface of the core over the center of the first decompression clearly caves, hollows, where samanalawewa concentric system of circular or oval-ring and intercept radial faults forming the bending energy bars. The softening and self heating mantle material is accompanied by transitions it into a different energy state, which leads to a sharp increase in volume and release of the surface in the form of the mantle diapir. This is comparable with the regular flares on the Sun, where similar processes occur in the plasma during its movement and distribution in orbits around the solar core from one layer to another. In parallel with the great centres of disintegration was born surrounding smaller centres satellites, over which within platformbased structures were formed geological ring structure (GCS) sverhnegativny - the nuclears and megastructures systems concentric circular or oval-annular and radial depth according to the MOU. In terms arching troughs of these structures stretching in zones forming them transform and extra-deep faults led to semiartinian over them chains GKS dome of depression and mixed type medium-range order. Their internal structure forms a symmetrically concentric grating ring, oval ring and radial faults. Similarly transform and superdeep faults they are in periods of tectonic-magmatic activation of the deep centers of the earth's core was fractured inlet channels to the surface for lifting of the mantle diapir or magmatic melts. Within GCS middle order are similar type of structure is of small order, formed the core faults.

The most promising areas of the search for ore deposits are surpriseee zone faults, where crustal magma sources or crossing the same or different grade of faults in the structures of the dome and mixed type of small order, because they are favorable areas for movement and localization of magmatic, and hydrothermal ore-bearing solutions, while the adjacent depression patterns of small order are natural structural traps for the formation of the richest placer gold deposits, the latina, tin and other metals.

Sources of oil and gas deposits are genetically related to mantle sources, which lowered the roots of transform and extra-deep faults are zones along transform radial, circular or oval ring faults in platformbased structures and along the depth zones are circular or oval-ring faults sverhnegabaritnyh - the nuclears and the mega-structures in non crustal magmatic chambers.

Figure 1 shows the predicted geological scheme on the world map.

Figure 2 is a fragment of this scheme, including the structure of secondary order "Coastal" Baikal-Amur sverhnegativny - nuclear.

The method is as follows.

On the basis of practical experience and information obtained in the process of large-scale mapping and POSCO evaluation work, the author has highlighted a number of continental geological ring structures with average diameters for platformbased - up to 15000 km; zwerglgarten - nuclears - 9000-3000 km and mega-structures of high order - 1500-1000 km. Internal structure of these structures determine the corresponding patterns of the lower order, including patterns of small and medium order with diameters respectively 600-300 and 45-5 km (figure 1).

All geological structures formed near the parallel zones of faults: transform for platformbased structures, superdeep for zwerglgarten - nuclears and mega-structures of high order, glubinnimi for structures of the middle order and the core structures of small order, oval-annular or ring fractures and radial network faults. All kinds of faults for each structure is the same rank and are located toward the center of the structures with a pitch of 1200 km and less for platformbased structures, 600-300 km for zwerglgarten - the nuclears, 400-200 km for mega-structures of high order, 20-8 km for medium-range order structures and 2-1 km for structures of small order.

One of platformbased structures - "Baltic" 1. Its longitudinal axis 14500 km oriented in a near-meridional North-Eastern direction, short - is 11500 km Core around which was formed this structure, known as the Baltic shield, which is determined by the same name. It is framed around the perimeter of an oval ring or oceanic transform fault. Similar parallel transform faults in increments of 1200 km in the direction of its center - the nucleus together with the clipping radial transform faults form the bending energy of the lattice structure.

The internal structure of the Baltic" 1 define geological ring structure (GCS): sverhnegativny - the nuclears, megastructures and the structure of secondary and malog the order as separate aggregations or intermittent and closed chains, determining cellular-reticulate structure.

From the South-West Baltic borders with comparable structure "Caribbean" 2 sizes axes 12600 and 10800 km, oriented in the meridional direction. The core of this structure is the link with North and South America. In the South-East structure "Caribbean" 2 bordered platformbased structure "South polar" 3, the average diameter of which is 16800 km Internal structure of these structures like the structure of the "Baltic" 1, but here the preponderance of segments of oceanic crust, where the formation of sedimentary shell and silicicola layer of the earth's crust. Together with oceanic platformversion structures Arctic, Pacific, Indian and Atlantic oceans are considered continental platformbased patterns form the structure of the crust.

In addition, the author has been allocated separately located from platformbased structures sverhnegativny - the nuclears and megastructures. So, in the far East according to the morphostructural analysis megaform topography of the land, coast, peninsulas, Islands and archipelagos on the outskirts of the Siberian and Chinese platforms was isolated and analyzed sverhbogatye - nuclear "Baikal-Amur" 4. The longitudinal axis of this structure is oriented in a submeridional behold the EPO-East direction and reaches 5300 km, and cross - 3700 km Framing GKS "Baikal-Amur" 4 oval-ring-in-depth fault reaches on the North coast of the Arctic ocean in the lower Colima, and on the South to its segment timed valley of the lower reaches of the Yangtze river's floodplain. In the East along the coast of Japan, the Kuril and Kamchatka arc he accompanied oceanic troughs 11, 02 km below the sea surface, operating underwater and above-water volcanoes and earthquakes. Therefore, it is considered as the area of benova and subduction, where it is believed that the oceanic crust moves under the continental. On the Western edge of this structure, the area of the break in the lake district. Baikal is accompanied by an active seismic rift zone and passes further South into the territory of Mongolia and China in areas of seismic activity. To the zone through radial depth of the fault coincides with the longitudinal axis timed straight section of the coast of the sea of Okhotsk North of the mouth rude. To the South along the valley can be traced resilence and lower reaches rsea and upstream rangari and chain ring and oval-annular depression secondary structures of the order of the Central part of the SCS "Baikal-Amur" 4. The edge of it on the North is bordered by two smaller sverhnegativny - the nuclears, the longitudinal and transverse axis which is s-3600 and 2900 km In the South it deeply penetrates into the next zwerglgarten - nuclear "Indonesian" 5, the longitudinal axis of which reaches 9000 km and oriented in the North-Eastern sub-latitudinal direction, and the cross does not exceed 7200 km GKS "Indonesian" 5 in turn, is bordered by the neighboring South-East sverhkachestvennoy - nuclear "Australian" 6, completing the chain. Its longitudinal and transverse axes, respectively 8400 and 6000 km GKS "Baikal-Amur" 4 and "Indonesian" 5 from the West border platformbased GKS "Baltic" 1.

For Paleozoic within the structure of the Baikal-Amur" 4 for performing its internal structure based megastructures and GCS middle order, there were favorable conditions for areal carbonate sedimentation due to the long break active tectonic-magmatic activity of the deep mantle centers of the earth's core. It is set by the outputs on the modern surface tectonic plates and scales, integument and olistoliths characteristic of olistostrome orogen formed, as a rule, organogenic limestones and reef difference. Subsequent new phase or cycle of tectono-magmatic activity of the deep mantle centers coincided with the beginning of the Mesozoic. This led to the replacement of carbonate sedimentation Terry is authorized and siliceous-clayey characteristic glisodin the subsurface. Alternating repetitions in it layered rhythms in the structure of the packs or sedimentary strata associated with the reflection of the oscillatory movements of the earth's crust, accompanied manifestations of tectonic-magmatic activity of these centers. With them were associated mass eruption of an underwater fissure volcanism of the basic structure with the formation of the incisions powerful reservoir bodies spiritof, carrying out the Foundation of numerous, often large, limestone xenoliths. Based on the findings in them fossils of the Paleozoic fauna, containing Mesozoic sediments, characterized by the poverty of whole residues macrofauna were unreasonably to Paleozoic age. The formation of siliceous sediments contributed to the intake of acidic solutions due to the differentiation of basalt magmas. At the same time dispersed and deposited in loose sediments of the ore-bearing solutions, rising to the surface in parallel with magmatic melts. Mobilization of trace elements in these strata was linked in the second half of the Mesozoic with dinamometricheskie processes that accompanied the explosive nature of the formation of large cavities and chambers subsurface crustal magmatic chambers, zapomnivshihsya mantle diapirs. Under these conditions in the sedimentary strata, containing scattered ore-bearing solution is, was the concentration of gold and platinum are often around a unified plant residues. This led to the formation of a large volume of deposits of the type known Sukhoi Log in so-called black-shale sequences.

On the place of depression GCS middle order mixed type in their Central part formed extensive lacustrine-alluvial plains with a trace over them regional river network. This is the most characteristically manifested in the formation of the valley rangari crossing of depression GCS middle order, the Central portion of which is characterized by a natural symmetrical arrangement over the area mentioned previously through the radial depth of the fault coincides with the longitudinal axis of the structure of the Baikal-Amur". The study of the internal structure of depression structures of medium-range order (depressions), promising deposits of coal, oil and gas, is possible using only wells exploratory drilling. The latest is already installed in China within the outer part, highlighted by the author dome GCS middle order in the pool ussouri rivers. It should be noted that in the Cretaceous time regression of the paleo-basin sedimentation had obviously oscillatory character followed by rhythmic manifestations of tectonic-magmatic activity of the deep centers and related emeticeski crustal magmatic chambers. In parallel with the upwelling over crust magmatic foci within a single dome structures of the middle order was the formation of new superimposed depressions or shallow depression structures in the form of compensating deflections. Here, due to the oscillatory movements of the earth's crust or base structure of the Baikal-Amur" was the formation of coal-bearing sub-continental basins of the type known urgalskogo and other

Within sverhnegativny - nuclear "Baikal-Amur" 4 the author on the basis of carrying morphostructural analysis of the relief of medium - and large-scale topographic maps, geological and geophysical data and interpretation of high-altitude aerial photography was selected geological oval-ring structure of the middle order mixed type "Coastal" (figure 2). The North-Eastern half, separated through the North-West of the deep radial fracture remained submerged at the bottom of the Gulf of Sakhalin and the Amur estuary at the end of incomplete regression of ancient oceanic paleo-basin sedimentation in the first half of the Cenozoic. From external framing this structure deep oval-ring fault to the Central part of it can be traced parallel fault zones of the same rank. The first is in the range of 20 km, the follow - through 12-10, savera the General - 8 km. this structure completes the chain of the Amur comparable oval-ring of mixed type GCS formed over the area of a bent or angularly twisting northeast radial depth of the fault. Through the basin downstream of the ussouri rivers it can be traced to the Central part of the structure of the Baikal-Amur" 4, where it is also timed to the Central part of the dome comparable and depression GCS middle order.

Within the structure of the zone parallel oval-ring of deep faults in control of a chain of shallow circular depression, dome and mixed type of geological structures of small order, the internal structure of which is similar to the symmetric structure of "Coastal". Their maximum diameter in the circular and the longitudinal axis in an oval ring structures reaches 40, medium 20, small and minimal 6-1 km. They are formed by zones of crustal ring, oval ring parallel and radial faults. The distance from the outer framing of the crustal circular and oval-ring in the direction of the core or Central part of these structures is adjacent to the interval 2-1 km. According to geological data GKS small order form complexly built a huge volcanic units of the Central type with separate recepacle of gerlovin and Caldera collapse, performed by breccias, tuffs, lavas of different compositions of Mesozoic-Cenozoic age, same subvolcanic magmatic bodies and granitoids.

The main attraction of this structure "Coastal" is the presence of large industrial indigenous deposits of gold "MNV"smaller "White Mountain" and a number of its occurrences set in the process-scale geological mapping and exploration. "MNV" timed structural-tectonic terms, the core or Central part of the oval-circular dome of the structure of small order, oriented long axis (30 km) above the zone of deep oval-ring fault, framing the Central part or core. In the range of 3 km from the border of the Central part to an external fault set is another area comparable parallel fault and the network of radial fractures. Similar internal structure characterized located to the South-West ring structure small order "Nakalista" with a diameter of 20 km and Dolinskaya" with a diameter of 10 km In the Central parts of the projected availability of comparable stocks "MNV" ore gold deposits of similar origin. Justification forecast is similar location is their Central parts of these are comparable dome structures over an area of deep oval-ring-fault structure "Coastal". This takes into account its permeability for magmatic melts of intermediate and acid composition, formed here and subvolcanic Intrusive bodies, as well as ore-bearing solutions. The forecast is confirmed by the presence within the outer part of these structures placer gold deposits.

The field "White Mountain" in the structural-tectonic plan is located in the core patterns "Coastal" on the site of the crossing of deep crustal fault with framing the Central part of the dome structure of small order, the diameter of which is 12 km away, and the entire structure - 21 km. It is a stockwork, where the enclosing volcanics processed in the hydrothermal rocks, decomposed to white clay, which gave the name to the top of the mountain field. The other three consecutive intersections crustal faults that form the internal structure of this structure with deep fault zone, to justify a search here for another three such deposits. They are possible only through the sinking of boreholes in connection with the arrangement above them parts of valleys of the river network, where practiced alluvial deposits.

Within the predicted and previously known deposits on the basis of the proposed method are also defined by promising local areas of possible formation of the richest ores what's posts pockets, white sea and other related surpriseee areas of the earth's crust at the crossing depth of fractures with depth and depth with the core. Concentrated in their stocks sometimes determine the profitability of the mine with more modest content of extracted minerals. In addition, when setting of ore deposits the proposed method provides for the forecast in the adjacent alluvial depression structures of small order, which are the natural structural traps for the formation of rich deposits of gold, platinum, tin and other metals, as well as forecast hidden and buried deposits within the chain structures of small order, above the deep oval-annular and radial in the North-Western sector, hidden under the cover of terrigenous turbidity marine sediments of Mesozoic-Cenozoic age.

Positive exploration results on the local forecast area will allow in the near future to establish extensive gold province in the far East within only one structure "Coastal", which is part of the structure of the Baikal-Amur" 4.

Preferably promising areas in the search of oil and gas fields are peripheral edge part of the dome, depression and the internal structure of mixed structures of the middle order, along zones transform of radial and circular or oval-ring faults and super-deep circular or oval-ring faults, in the part where there is no crustal magma sources. Thus, the predicted oil field in the structure of secondary order "Coastal" allocated land to the North-East from the transverse radial depth of the fault of this structure along the oval-ring-in-depth fault of sverhnegativny - nuclear "Baikal-Amur" 4 in the Sakhalin Bay. Known oil field in Sakhalin, clearly timed along the depth of the ring fault, as well as the known oil and gas fields in platformbased the structure of the "Baltic": "Ural" 7 (Tatarstan), "Western Siberia" 8 (Tyumen), "Caspian", located along zones transform ring faults, and oil and gas fields in the Persian Gulf 9 and the Red sea 10 along the radial transform faults confirm the essence of the proposed method for the prediction of oil and gas fields.

Suggested by the author of the way of large-scale forecast fields of any mineral resources on the basis of the establishment of the real structural-tectonic predestination, causing localization of endogenous fields of Genesis in the most permeable knots is x and the zones of the earth's crust, opportunities replenish mineral reserves and will find, in his opinion, the wide industrial application.

A method for predicting mineral deposits, including the identification of geological structures by defining them in promising areas of the search fields, characterized in that secrete large geological planetary order platformbased structure with an average diameter of up to 15,000 km, and their boundaries sverhnegativny - the nuclears - 9000-3000 km, megastructures high order - 1500-1000 km and dome, depression and mixed-type structure in the middle order - 600-300 km and structure of small order - 40-5 km, and there are separate sverhnegativny - the nuclears and megastructures with the corresponding structures of the lower order, with all geological structures formed near parallel zone faults: transform - to platformbased, in-depth - for zwerglgarten - nuclears and mega-structures of high order, depth - to medium-range order structures and core - structures of small order, circular or oval ring network and the radial faults with this transform, in-depth, in-depth and crustal faults have the same ranking for each structure and are located toward the center of the structures with step 1200 km is less for platformbased, 600-300 km for zwerglgarten - the nuclears, 400-200 km for mega-structures of high order, 20-8 km for medium-range order structures and 2-1 km for structures of small order, and promising area forecast for ore deposits determine the structures of the dome and mixed type of small order, genetically connected with the core magmatic centers and located above the fault of a different order or at the intersection of the same or different grade of faults, for placer deposits in the area of near-ore deposits in the adjacent depression structures of small order, and for oil and gas in all the structures of the middle order along zones transform radial, circular or oval ring faults and along zones superdeep oval-ring and ring faults in the part where there is no crustal magma sources.
