Structural Characteristics Of The The Huachanggou Gold Deposit And Its Control On Gold Deposits,

The Huachanggou gold deposit lies in the south of Mianlue Fold bend, in the triangle area of Mianluening , the south of the Qinling Mountain orogenic zone .This deposit's happening and development have been controlled by ductile zone, as ductiled gold deposit.There have obvious warmhearted water deposited feature in the part of layer of mining area . Warmhearted water deposited eruption of sea floor pyrite rolled cakes have been discovered, in the layers of 1a, 1b, 1c and so on. Some warmhearted water deposited feature mineral could been seen under the microscope, such as tourmaline ect. Warmhearted water deposited eruption of early phase pyrite's rolled cakes is one of gold mine bed mine source. Based on the rock's chemical analysis and compare of rare-earth element, it can see that the deposit gold origin chiefly possess two kinds: (1) the volcanic rock; (2)golden fluid medium.Minerals in deposit are made up simpler, the metal minerals are pyrite, chalcopyrite in second, and littler natural gold; the veinstone minerals are quant, feldspar and carbonate. The structure of mineral stone is priority to dip-dye shape and veins shape; the framework of mineral is composition with self form , semi-self form, its form, embody composition and false appearance composition in second.The Huachangguo gold mine bed lie in under-middle of the Sanheke group of D, there has mine bend in the Bike group, south of the Sanheke group of D. The gold mineization is found in all crag of entire mining area, it's obvious pertain to the structure controlled mine, have no very much great relationship in the crag straturm.Exhibition of the deposit is controlled by the regional ductile zone, and the ore's distribution has been controlled by the secondary ductile zone (controlled mine ductile zone ), the brittleness structure of Later stage possess the specified reconstruction and damage to the mineral ore, at the same time it also strengthened gold once more wealthy anthology. The deformation intensely mechanism is the main kinetics and kinematics mechanism, which controlled the gold mine bed's form. Ductile zone is anxious the brining guides the structure in mine and accuseeing the mine, Rong Kuang constitutes.The places of gold ore is not only in the powerfulness place, but also in the place of tenacity-brittleness and the place of powerful deformation girdle place to the feeble the deformation in Ductile zone gold bed.
