广东某热液型钨矿对土壤与地下水生态环境的影响研究

Impacts on an ecological environment from a hydrothermal tungsten mine in Guangdong province

通过对广东省某热液型钨矿及其所在地区土壤背景值的对比研究,认为该矿区对于周边环境而言,是一个多元素、多成因的异常源,主要异常元素涉及As、Cd、P、Bi、W、Au、Ag、Sb、Cu、Zn、Pb、Ni、Co、Ti、V、Si、Mo、B。由成矿作用、地质背景、人为活动交互形成复杂的综合异常区。对区域内表层与深层土壤、地表水和浅层地下水的系统监测结果表明,该热液型钨矿各异常元素已对周边水土生态环境造成影响,应实施水土污染治理工程。

We investigate hydrothermal tungsten mine and the geological background value of its surrounding area, and demonstrate that the mine is a major source of multiple element anomalies. The most significant anomalous elements include As Cd P Bi W Au Ag Sb Cu Zn Pb Ni Co Ti V Si Mo B. Although the anomalies result from the combined effects from mineralization, geological background and human activities, after thoroughly investigating the surface soil, deep soil, surface water and shallow underground water, we suggest that negative impacts on the ecological environment have been caused by the hydrothermal tungsten mine.
