West into the lead and zinc (silver) a new understanding of gold deposit


It is only from one slice with the other strata of mutual relationship between the judge, from the River Luo Hui County into the County area to the river area, one can clearly see a Silurian Devonian rocks composed of thrust slices In the Triassic, Jurassic on one, but the official store mélange thrust deep slices and on top of it, thus pulling the West into a region of a slice of the times thrusting may occur in one generation. 3 output features of the West ore deposits of the ore deposits Tanaka Devonian strata in addition, there are (old) Proterozoic. Dam and mine ore body ore rocks are mainly schist and marble, Lijiagou mine are mainly marble. Produced in the Devonian rocks in the ore deposits are mainly crystalline limestone and crystalline limestone or interbedded phyllite, such as the completion of Jiashan, Jiashan Tang, Pages River and other deposits. Therefore, very large dam and deposit is not in the Devonian, but in the Proterozoic strata. Tanaka ore deposits in the West all the orebodies are located in the structure of foliation,[link widoczny dla zalogowanych], and bedding plane (S.) No direct relationship. Deposit is obviously controlled by structure, its output has the following three parts: 1) a deep schist, gneiss rock film in a marble deposits,[link widoczny dla zalogowanych], such as dam and a Lijiagou deposit, which is active pull a rock film thrust the formation of deposits, 2) produced in the strike-slip zone in the deposit, such as the completion of Jiashan, Jiashan Tang deposit, the film is a rock formation in shallow deposits; 3) produced in the stripping of a detachment zone of the deposit, such as gold settled down fork gold deposit and adjacent points,[link widoczny dla zalogowanych], coke ditch, sharp cliffs ditch, grass off deposit, the film is the formation of shallow rock deposits. Tin mineralization in the West, produced in the initiative to pull a rock thrust the most important film of the deposit, followed by strike-slip zone, and then followed by the stripping of the deposit slip zone. Tanaka specific ore deposits in the West ore-controlling structure, or by tectonic foliation composed of mylonitic foliation-A sheath fold or fold. 4 Some problems on the mineralization (1) us from the starting characteristics of ore deposits that formed during the Yanshan it a Himalayan. West ore body into the region are produced in the Proterozoic, Devonian strata in the structure of foliation, the era of the formation of obviously later than the Devonian strata. (2) cluster of ore deposits is subject to pull the West ore field. Tectonic slices thrust control】. When the deep, ore-forming fluid subsystem and the pull of a thrust slice forming system constructing a sub-system to achieve a dynamic balance between order time Geochemistry of ore Tanaka to form deposits in the West. Therefore, the West ore field (including wind-Pacific region) are not deposits in a jet of hot water (gas) or the transformation of sedimentary deposits, but later in the Devonian syndepositional of epigenetic hydrothermal (water) deposits. (3) Lijiagou dam deposit is forming a sub-system and take the initiative to pull the fluid thrust deep slice of a dynamic and orderly balance to the formation of deposits, is a piece of deep rock rock, marble deposits; completion of Jiashan, Deng Jiashan is forming fluid subsystem and strike-slip fault in order to achieve dynamic balance of sheath folds in the formation of deposits, is a crystalline limestone in the shallow slice in the deposit; and coke ditch, sharp cliffs and other deposits in the ditch and the stripping is A detachment structure to achieve balanced and orderly formation of deposits, is a shallow rock sheet deposits in carbonate rocks. Therefore, the West ore deposit Tanaka different characteristics,[link widoczny dla zalogowanych], size and location, is subject to pull a tectonic thrust slices and their respective control of structural conditions,[link widoczny dla zalogowanych], while the concentration of deposits controlled by the pull of a full output of the thrust slice structure, composition a constructor. Ore-forming system. The mineralization model to better clarify the Tu issues raised by academicians. Thanks: field work funding by the Hong Kong Foundation, grateful.
