湖南双峰包金山金矿土壤地球化学特征及其指示意义

Geochemical Characteristics of Soil and its Indicating Significance in Baojinshan Gold Deposit, Shuangfeng,Hunan

通过对矿区实施土壤地球化学测量,确定Au为直接示矿元素,W、As、Cu、Sb、Hg为其指示元素;Au、W关系非常密切,异常叠加良好,构成南北两个成矿带,其中南部异常带的中心部位与包金山矿区现采区一致,足以见Au、W组合异常对找矿的指示意义;土壤测量北部异常带与南部异常带相距颇近且异常分布特征相似,应予以重点关注。

Through the implementation of soil geochemical survey,determined that Au is an direct element indicating the mineral, while the elements of W、As、Cu、Sb、Hg as the indicated elements. Au and W are closely related and have good abnormal superposition, forming two mineralization belts in the south and the north. The central part of the anomalous belt in the south is consistent with the present mining area of baojinshan mining area, which is enough to show the indicative significance in prospecting by Au and W combination anomalies. Soil measurements of the northern and southern anomaly zones are close to each other and have similar abnormal distribution characteristics, which should be paid more attention.
