摘要
那更康切尔沟银多金属矿床是近年来发现的次火山岩型矿床,地处东昆仑成矿带东段。为了缩小找矿靶区,在那更康切尔沟矿区开展了1∶1万土壤地球化学测量,圈定了9处综合异常;进一步对综合异常进行查证,圈定5条银矿化带,9条银矿体。银矿体主要赋存于上三叠统鄂拉山组火山岩中,受北西向断裂构造控制;围岩蚀变主要有黄铁矿化、褐铁矿化、软猛矿化、黄钾铁钒化、硅化、碳酸盐化等。该矿床达大型规模,个别矿体总体控制程度低,显示出较好的找矿潜力,有望取得较大找矿突破。
The Nagengkangqieergou silver polymetallic deposit is the volcanic type ore deposit which is discovered in recent years,located in eastern Kunlun metallogenic belt.According to the 1∶10 000 soil geochemical survey in the mining area,the paper marked out 9 comprehensive anomalies to make the target area smaller.Further verification of the comprehensive anomalies framed 5 silver mineralized belts and 9 silver ore bodies.Silver ore bodies mainly occur in the Triassic Ela mountain group volcanic rock and are controlled by the NW fault.The wall rock alteration are mainly pyrite,limonite,soft hard mineralization,jarosite alteration,silicification and carbonatization,etc.The deposit amounts to large scale and individual ore bodies have low overall control degree,which shows good potential for exploring mineral resources and expectation to obtain major prospecting breakthrough.
