白银厂黄铁矿型矿床,是我国已知铜矿床的重要工业类型之一.矿床中除铜、硫、金、银具有工业价值外,还有铅、锌、硒、碲、镉、铟、铊、镓、铋、汞、砷等,也具有综合利用价值. 地质概况矿床产于北祁连加里东地槽褶皱带中寒武统变质火山岩系中.区内火山岩发育,分异完全,从基性到酸性、从浅成到喷发乃至喷发沉积均可见到矿床产于石英角斑岩中.矿床呈扁豆状、似层状、脉状等产出,常见膨胀、狭缩、分枝、复合、尖灭、再现等现象.矿体走向280～300,倾向南西,倾角50～80°.矿石成分复杂,主要有黄铁矿、黄铜矿,其次是闪锌矿、方铅矿及少量
The Baiyinchang pyrite deposit is one of the most important industrial types of copper deposits in China, except for the industrial value of copper, sulfur, gold and silver, as well as lead, zinc, selenium, tellurium, cadmium, indium , Thallium, gallium, bismuth, mercury, arsenic, etc. Geological Survey Deposits are produced in the Middle Cambrian metamorphic volcanic series in the Galliferong Gulch Fold Belt of the North Qilian. The volcanic rocks in the area are well developed and completely differentiated, From basic to acidic, from shallow to eruptions and even eruptions can be found in the deposits produced quartz quartz porphyry deposits are lentil, like stratiform, veins and other output, common expansion, narrowing, branching, Complex, pinchout, reappearance, etc. The orebody moves towards 280-300 with a tendency of southwest and a dip angle of 50-80 ° .The composition of ore is complicated with pyrite and chalcopyrite, followed by sphalerite, galena and a few
