Study Of The Ductile Zone And Its Control Over Metallization

The longquanzhan gold mine in the middle section of the Yishu fault zone is located in Yishui city Shandong province. The longquanzhan gold mine is a typical ductile gold mine, which has been controlled by ductile shear zone. this mine lies in Chinese east biggest fault zone—Yishu fault zone, which belongs to different structure overlay compound position, It is a very prospecting ore-forming region.Archeozoic layer in the district is a set of volcanic and deposit build, which is the character of greenstone belts. Archeozoic layer in the district golden background value is higher than Clark value obviously. It is one of the major mine sources in this district golden mine. Based on the rock analysis under the microscope and compare of the rock chemical analysis, it can see that the mineral gold origin chiefly possess two kinds: ① the volcanic rock; ②golden fluid medium of hot liquid.Minerals in mine are made up simpler, the metal minerals are pyrite, chalcopyrite in second, and little gold; the veinstone minerals are chlorite, quartz, sericite and feldspar etc. the structure of mineral stone is priority to strip shape, brecciform, veins shape, dip-dye shape and gobbets shape; the framework of mineral is composition with self form, semi-self, its form, embody composition and substitute composition in second.The longquanzhan gold mine bed lies in yishui-tangtou fault zone and gongdanshan horst. The gold minerization 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 shear zone, and the ore' s distrbution has been controlled by the secondary ductile shear zone(control led 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...
