私采私淘已退役钨矿重金属元素异常成因及其生态环境效应

Influence of a Hydrothermal-type Tungsten Deposit in Guangdong Province on Ecological Environment

本文通过对广东省某钨矿及其所在镇与市土壤背景值的对比,认为该区域是一个多元素、多成因,涉及到As、Cd、P、Bi、W、Au、Ag、Sb、Cu、Zn、Pb、Ni、Co、Ti、V、Si、Mo、B十八个元素,由成矿作用,地质背景,人为污染交互影响形成的复杂的综合异常区。对各异常元素对该区域表层土壤、深层土壤、地表水和浅层地下水的影响进行了详细研究,认为该热液型钨矿已对周边生态环境造成了影响。

This paper emphatically studies the relationship value. The anomaly genesis in this area is very complex, and have various types of anomaly elements, for instance, between a hydrothermal-type tungsten deposit and soil background including mineralization, geological background and human activity As,Cd,P,Bi,W,Au,Ag,Sb,Cu,Zn,Pb,Ni,Co,Ti,V,Si,Mo and B. This paper mainly studies surface soil, deep soil, surface water and shallow groundwater in the anomaly area, providing evi denee that the hydrothermal-tvpe tungsten deposits do some harm to the eeo-environmental in this area.
