新疆某铜金矿地球化学找矿评价

Evaluation of searching for ores with geochemistry method in a copper and gold mine in Xinjiang

利用水系沉积物测量方法 ,在地球化学景观为高寒山区的新疆某地圈定异常 ,筛选出对成矿有利的Cu、Mo、Au、Ag等元素组合异常 3处 ,通过对成矿地质环境及元素异常的综合分析 ,认为其中一处异常为矿致异常 ;利用岩石测量对其进行分解 ,评价异常 ,逐次缩小靶区 ,进而对该地区做出初步的找矿评价 ,确定了有利找矿的地段 .最终发现矿化点多处 ,并对两处进行了F级科研预测储量估算 ,认为该地区可作为寻找中 大型铜。

First,the abnormal area have been marked out in a place in Xinjiang where it has the feature of high and cold mountainous region in terms of geochemistry by the stream sediments survey method.Then,it has choosen three places in which the elements such as Cu,Mo,Au,As and some others are combined and favourable to the formation of ore deposit.By the comprehensive analysis of geological conditions and the abnormetity of the elements,it has considered that one of the three places is caused by ores.Therefore,decomposition of the elements has been done by the rock survey method.And the abnormal has been also evaluated.The target areas have been gradually narrowed.Thus,the evaluation of searching for ores have been prelimenarily obtained,and the better places for searching for ores are determined.Finally,it has found many mineralized spots,of which two of them have been evaluated for their deposits at F grade by scientific estimation.It has concluded that this area can be regarded as a base of a general survey of medium*.sized copper,multimetal and iron.
