1. Law of mineralization
(I) time distribution law
The gold mineralization times in the Jiaodong area are studied much, and the Dingzheng (2014) roughly divides the mineralization of Guidong precious metals and non-ferrous metals into six stages: namely late triassic period (205 Ma), early late Jurassic period (160-155 Ma), early chalky period (135-125 Ma), middle period (125-115 Ma) and late period (115-100 Ma), and late chalky period (100-90 Ma). And points out that the mineralization action background is gradually changed from the stretching environment to the extrusion environment and then to the large-scale stretching environment from morning to evening, the mineralization elements and the mineralization types are gradually evolved from simple to complex, the mineralization depth is gradually reduced, the mineralization scale is changed from small to large to small, and the influence of the depression of the ancient Pacific plate on the mineralization action of the precious metals and the nonferrous metals is emphasized.
The former people develop more researches on the times of mineralization of gold and polymetallic minerals in northeast China of Jiaolai basin, and the acquaintances are the middle-late stages of early chalk. The discovery of gold mine in Liaoshang style greatly expands the concept of finding mine. Through research, the gold and multi-metal mineralization in the northeast region of the Jiaolepi basin is considered to be mainly divided into two stages, namely the middle-late stage gold and copper-molybdenum multi-metal mineralization in early chalkiness, and the mineralization time is 125-115 Ma; late chalkiness-ancient new gold mineralization, with mineralization time (58 ± 11) Ma. From the mineralization characteristic of gold deposit in Liaoning, the late chalkiness-ancient and new chalkiness mineralization is superposed in the early chalkiness-late gold mineralization, the mineralization background is an extension environment under the background of extrusion dynamics, and the mineralization depth becomes shallow.
(II) spatial distribution law
(1) Law of rock control of regional structure
In the region, 4 NE fractures such as Takamura, guocheng, cliff, yuli and the like are fractures of the basin edge in the northeast region of the Jiaolei basin, so that the distribution of invasion rocks and volcanic rocks from the chalk period is controlled. These fractures are gradual progression from substrate fractures to super shell fractures during the thinning of the chalky dike, and are the primary transport pathways for the magmatic-volcanic activity. From the exposure of rocks and mineral deposits, the fracture control of the peaches is more obvious, and granite (tooth mountain, hodgkin rock mass) in the Vietnamese mountain period and volcanic rock in the Qingshan period are distributed along the fracture sides of the peaches; the eruption of the volcanic rocks in the green mountain period near the cliff fracture is less influenced by the thinning degree of the crust, the denudation degree of the earth surface, the depth of the rock mass invasion and the like. In this respect, the basin between the fracture of the peachamus and the fracture of the Guo city belongs to an open system, and the gas and liquid generated by the magma-volcano activity are not beneficial to preservation, which may be an important reason that no gold deposit is found in the West of the fracture of the Guo city; in contrast, in the east region of Guo city fracture, the thickness reduction degree of the crust is low, the thicker fine clastic rock is deposited on the Laiyang group in the basin or the lifting and denudation degree is low compared with the west region, so that the escape and loss of magma-volcano gas-liquid are prevented, the gold-containing gas-liquid is stored, and large-scale gold mineralization is performed in the region.
(2) Law of structure control
The ore bodies found in the area are all strictly controlled by a fracture structure, except for the fact that the Kuangjiajin ore exists in a fracture zone separated from the spoiled core rock of the near EW direction magpie mountain; other ore deposit bodies are present in the NNE-NEE directional fracture structures of the upper and lower plates of the main fracture of Guo city or cliff (such as gold ores of Guo city, liao, west waterlogging mouth, weeping willow and Nanguo of the lower plate of Guo city fracture, large-inner-ditch gold ores of the lower plate of cliff fracture, and Songhua-ditch gold ores of the upper plate). The NE-oriented structure controls both the distribution of gold deposits over the area and the occurrence of ore bodies. NE is broken towards Guo city, cliff is broken and ore control characteristics are obvious, mineral deposits (points) of Guo city, liaoshang, anterior weeping willow, south fruit and the like are sequentially distributed in the NE direction from south to north, and are controlled by the breakage of Guo city; gold deposits (points) in Song Jia ditch, big inner ditch and the like are controlled by cliff fracture and are all produced in dense fracture zones of upper and lower plates of cliff fracture. In the area, gold ore bodies in the Liaoshang and Song Jia gou are NE-oriented, the trend is mainly SE, and ore bodies found in the shallow part of the gold deposit in Guocheng are mostly oriented to NW. According to the space position of the basin, the basin inner ore control structure (Song Jia ditch, big inner ditch gold deposit), the basin edge (basin bottom) ore control structure (Ku Jia Kuang, west wellhead gold deposit) and the basin outer edge ore control structure (Guo city, liao Shang gold deposit) are divided.
a. NE to dense fissure zone
The ' Song ' house ditch type ' gold ore is subjected to dense fracture ore control, the scale is small, thick and large industrial ore bodies are mainly enriched in the dense fracture zone in the direction of partial NE, and almost no industrial ore body is enriched in the direction of partial NEE; the main section is inclined to SE, and the inclination angle is generally 45-80 degrees. The cracks are totally steeply inclined, and only the local inclination angle is relatively slow and is less than 30 degrees. The ore body of the Song Jia channel gold deposit is strictly controlled by tensile steep dip fracture and dense crack zones, the tendency is consistent, and the dip angle is similar. The ore body is generally small in scale, but still shows the characteristic that the ore body is relatively thick and large at the position where the dense crack zone is inclined to be gradually steep. The ore body is present in a series of parallel fracture and dense fissure zones and is strictly controlled by the fracture and dense fissure zones, the ore body is locally laterally inclined to NE, and the lateral inclination angle is about 30-50 degrees.
b. Inclined or conjugate structure
The shallow ore-holding structure in the "guo-city" gold area is mainly in the NNE direction, and the second in the NEE direction. Trends NW or SE, with a predominance of NW trends and lower dip. The inferior-lying NNE direction and NEE direction are broken, and the section is in a gentle wave shape. The ore control structure is divided into two forms, namely an inclined form and a conjugate form. Controlled by the equidistant and oblique-column rule of the gentle dip fault, the ore body is in the characteristic of layered enrichment; the interweaving of the ore body in an X-shaped pattern into a net is a representation form of conjugate shear fracture on a section.
c. EW to disconnect fault
The mineral body of the gold deposit of the formula of Gorgonia kuangjia is controlled by a detachable fault structure formed by a stone system of metamorphic nuclei in the late Jurassic-early chalkiness stage; the detached fault main slip surface is a gold mineralization zone, the output of an ore body is closely related to lithology of graphite-containing schist and marble rocks in the slip zone, and the graphite-containing schist provides an oxidation-reduction interface for mineral precipitation and plays a role in shielding; the development of the marble lens body is easy to form geochemical barrier in the process of forming ore due to the active chemical property of the marble lens body, so that gold in the ore liquid is precipitated; the thick part of the ore body is produced at the part which changes from steep to slow, the main ore body and the rich ore section have the rule of lateering to the south; the final positioning of the ore body may be influenced by the NE left walking gliding structure, and the ore body may have the phenomena of overlapping and left walking gliding, so that the mineralized lens body and the laterals thereof are consistent with the regional structure line. The structure mainly controls kuang-jia-kuang-jin-shi in the district, and the mineral deposit produced at present is kuang-jia-kuang-jin-shi.
d. NE is to slippage structure
Gold mine in Liaoshang type has the characteristics of sectional enrichment, steep ore body in shallow part and slow ore body in deep part; the shallow part ore body has small scale, poor regularity and steep yield, is controlled by a NE-direction slipping structure zone, the ore bodies are often grouped, the shallow part structure shows extrusion property, and the mineral-containing solution mainly plays a role of substitution; the deep ore body has large scale and slow production state and is controlled by the main structure surface, the thick part of the ore body on the section plane is often produced at the turning end which is changed from steep to slow, the deep structure shows tensile property, and the mineral-containing solution is mainly filled.
e. Equidistance/symmetry distribution rule of large-scale deposit
Mineral deposits produced along the area of Guocheng-Nanguo have the characteristic of near-equidistant distribution, gold deposits (points) such as Guocheng, liaoshang and anterior weeping willow are sequentially produced from south to north, and are all produced from the east protruding position of the stratum of the Jingshan group when viewed on a plane, and the position can be the center of a sliding structure in the area; the ore deposits on two sides of the herding cattle mountain rock body are symmetrically produced, such as Liaoshanggold ore, western waterlogging gold ore (south section), anterior weeping willow gold ore and western well mouth gold ore deposits.
(3) Depth of formation and occurrence elevation
The temperature measurement of the fluid inclusion is estimated, the depth of the currently exposed gold deposit, such as Guocha, songhui, kuangjia and the like formed in the middle-late stage of early chalkiness, during mineralization is approximately 5-8 km, and the erosion suffered in the area is at least 5km +/-compared with that during mineralization; the depth of the Song family ditch gold deposit formed by late chalk-ancient and new era is 1.2-2.7 km, the existing depth is 0.8-1.2 km, the denudation depth of the Song family ditch gold deposit in the Liaoning neighborhood since the new generation is not large, and the denudation depth is 0.5km plus or minus.
(III) relation between alteration and mineralization of surrounding rock
Because the gold deposit produced in the region is different from surrounding rocks of the ores, the surrounding rock alteration of each ore deposit type is different, the middle-late mineralization alteration action in early chalkiness is stronger, and the method has certain regularity and takes silicification and sericite as marks; the late chalkiness-ancient and new chalks are mainly filled, the alteration of surrounding rocks is not obvious, and the carbonate is used as a mark. The relationship between bed-type wall rock alteration and gold mineralization is summarized below.
(1) Song family ditch type gold mine and surrounding rock alteration relation
The change of the surrounding rock mainly develops yellow iron seriummatization, silicification, kalification, carbonation and the like, wherein the yellow iron seriummatization and silicification are closely related to gold mineralization, and the yellow iron seriummatization and silicification change parts with strong degrees often form gold-rich ore bodies. The alteration gradually weakens with distance from the ore body, and the zonation phenomenon from the ore body to the surrounding rock is from gold-containing yellow iron sericite conglomerate → conglomerate.
(2) Alteration relation between kuangjia kuang gold mine and surrounding rock
Under the control of detaching fault, the kuangjiakuangmi has certain vertical zonation in space, and can be divided into the following parts from the ground surface to the underground:
argillization-carbonation belt: mainly developed in the fault mud zone above the upper detached fault plane, which mainly consists of illite, quartz, calcite and ferrimanganese hydrochloride, and its mineralization is inferior to silicified-sericinized zone, which determines the approximate upper limit of the mineralization zone.
Siliconized-sericinized tape: the broken dolomite rock-change rock mainly develops in the middle of the detached fault zone, develops long-quartz structure breccia, long-quartz broken rock, yellow-iron mineralized long-quartz structure breccia and yellow-iron mineralized broken dolomite marbles altered rock, mainly comprises metal sulfides such as quartz, sericite and pyrite, and the pyrite is distributed in a block shape, a dense dip-dyeing shape and a net vein shape, and the broken rock in the zone is strong and the alteration is strengthened, thereby forming a main development existence part of an ore body.
Silicidation-sylation zone: mainly located in the mylonite zone below the lower detached fault plane, the potassification is only partially visible, the mineral component is basically the original rock component, and the star-like pyrite mineralization and weak sericite micanization can be seen.
(3) Change relation between Liaoshang type gold mine and surrounding rock
It is mentioned that the gold ore of the formula Liaoshang is mainly filled, is filled in a vein shape and a network vein shape, the alteration of surrounding rocks is not obvious, the environment of an ore forming fluid is an alkaline environment, and the gold-containing pyrite carbonation is the most main alteration mark.
(IV) enrichment rule of ore-forming elements
From the distribution of elements in rocks, the types of elements with high abundance among sedimentary rocks, metamorphic rocks and magmatic rocks are different, but the elements of Au, mo and W in the region are all higher than the average value of the crust of North China in various rocks and belong to a high background region. The distribution of elements in the region is non-uniform, elements such As W, bi, mo, cu, pb, au, ag, as, sb, hg and the like are enriched, even part of elements are mineralized, and deep hot liquid mainly moves along a fracture zone and is enriched nearby the fracture zone; the low-temperature elements Au, hg, as and Sb in the zone are obviously superposed, and Au is the main attack mineral species in the zone.
R-type clustering analysis and factor analysis show that two-stage mineralization superposition of Au exists in the region, the first-stage mineral elements are combined into Au-Ag-Cu-Mo (-Bi), the enrichment mineralization of the elements in the period corresponds to middle-late gold and molybdenum ore deposits of early chalkiness, and the enrichment mineralization of the elements in the period is closely related to activity of invasion rocks in the Vird mountain period or magma-volcano in the Qingshan period; the other stage of mineralization is similar to low-temperature hydrothermal mineral deposit formed by late chalkiness-ancient and new times, and also proves that the first stage of low-temperature hydrothermal mineralization exists in the region. The Au-As element combination can provide reference for in-zone prospecting work.
2. Ore-finding mark
Geologic mark
From the lithology of the near-ore surrounding rock, the Jingshan group marbles, the graphite-containing oblique-long-piece gneiss, the oblique-long-angle amphibole and the Yanshan period basic gangue are closely related to gold mineralization and can be used as an ore finding mark, particularly, the layer position of the marbles in the Jingshan group stratum is easy to form a structural slippage (crushing) zone, and the chemical activity of carbonate is strong, so that gold mineral liquid is easy to precipitate in the zone, and a gold ore body is formed, and the exact understanding of the distribution of the marbles stratum is beneficial to the search of gold ores; in addition, the barite vein produced at low temperature is also an important marker for low-temperature hydrothermal activity.
From the perspective of surrounding rock alteration, silicification, pyrite mineralization and serite petrochemistry are indications of existence of mineralization alteration and are mineral exploration alteration marks of moderate-temperature hydrothermal vein type mineral deposits such as kuangjia, songhui, guocheng and the like; the vein-like pyrite-carbonation is the prospecting mark of shallow low-temperature hydrothermal deposit in Liaoning. The weathering of the surface of the ore vein in the area is strong, the metallic minerals are mostly oxidized and leached to form black or reddish brown honeycomb outcrops, the weathered marble rock is yellow brown, the erosion zone in the sedimentary rock is grey black after weathering, the erosion outcrops on the surface can also be used as an ore finding mark.
From the view of ore control structure, the structure slippage (crushing) zone is a main structure mark of ore finding in the zone, and the structure turning part and the fault concave-convex part are favorable sections of gold ore forming. Various types of gold ore bodies are found on the periphery of the basin, and most of the gold ore bodies are present in slippage (crushing) structural belts inside the metamorphic rocks of the Jingshan mountain crowd and contact belts between the metamorphic rocks and exquisite dilongs. Therefore, the area with the characteristics in the area is an important section for finding the mine.
(II) geochemical Mark
The surface of the ore body is exposed and nearby, and the gold element abnormality (soil, rock or water system sediment geochemistry measurement) is obvious. Therefore, the gold detection abnormity is also a very effective ore finding mark. The two-stage gold mineralization effect in the region is shown in the aspects of the mineralization epoch, the geochemical characteristics and the like, the abnormal combination of the mineralogical elements Au-Ag-Cu-Mo (-Bi) in the geochemical measurement is the geochemical prospecting mark for the medium-temperature heat liquid vein type deposit (the first stage), and the Au-As is the geochemical prospecting mark for the low-temperature heat liquid vein type deposit (the second stage).
(III) geophysical sign
Because the polymetallic sulfide in the ore is a good conductor of electricity, the abnormality obtained by the electrical method measurement can guide the prospecting. At present, a plurality of geophysical prospecting methods such as a CSAMT method, a seismic method, a high-density electrical method, a gamma energy spectrum measurement method and other geophysical prospecting methods (Liguanming et al, 2000; yang jin et al, 2000f; liguang river et al, 2001; shikun et al, 2001; zangqing et al, 2001; chenrelin et al, 2003; roxipeng et al, 2010; liujinyou et al, 2013; guo Jiang et al, 2014) are developed in gold deposits of Tan Qiang basin northeast regions, kun ditch (Kukun), guo City et al. It should be emphasized that, in the region of the Jingshan mountain marble, a part of the region contains more graphite which is also a good conductor of electricity, and especially attention should be paid to distinguishing the metal sulfide induced abnormality from the graphite induced abnormality in the electrical measurement.
