| 摘 要： | 南金山金矿是北山地区典型的浅成低温热液型金矿床,原20万化探扫面中在该矿床处存在W、Mo等高温元素异常组合,明显异于一般浅成低温热液矿床仅存在中低温元素异常组合。作者在系列成矿找矿思路的指导下,采集了南金山金矿床不同深度的地球化学样品,剖析该矿矿床特征、蚀变矿化特征、成矿元素的富集规律,指出该矿床是一典型的高硫型浅成低温热液矿床,矿床高温元素W、Mo,中温元素Cu向深部增高。并通过与典型铜金矿床地化特征、国外高硫型浅成低温热液型矿床与相关铜金矿床空间配位的类比,提出了南金山金矿深部存在斑岩型铜矿的可能。

| Abstract: | The Nanjinshan gold deposit is a typical epithermal deposit in the Beishan area,Gansu Province. As shown on the map of original geochemical reconnaissace of scale 1:200000,there as an abnormal combination of W,Mo and other high-temperature elements in this deposit,significantly different from general epithermal deposits where exists only an abnormal combination of low temperature elements. Under the guidance of the prospecting thought based on series mineralization theory,we have collected geochemical sampl... |
