摘要/Abstract

摘要： 在2008、2009及2012年相同时段内，对西藏驱龙铜矿区内及外围水系中重金属离子及水化学采样进行分析，结果表明，水体中Cu、Zn离子含量较高，水化学类型为硫酸盐型，pH均值为5.57，硫化物的风化溶解造成水体中SO₄^2-异常，且与Cu²⁺呈显著正相关关系。金属硫化物氧化释放出大量重金属离子，并随地下水、地表水迁移富集，其浓度变化趋势与矿床大小及赋存位置一致，Cu²⁺水文地球化学特征与铜矿床类型、规模等存在成因联系，其为寻找该类型矿床建立了良好的水文地球化学找矿标志。

Abstract: In the same period of 2008，2009 and 2012，water from inside and outside of Yulong copper area in Tibet are sampled to analyze its heavy metal ions and hydrochemical status.The results show that，the contents of Cu，Zn ions are higher in water with hydrochemical type as sulfate and pH value 5.57.Weathering and dissolution of sulfide results in SO₄^2- anomaly in the water，and this anomaly is positively correlated with Cu²⁺.Large amounts of heavy metal ions are released from metal sulfide oxidation，and then are enriched with migration of underground water and surface water.Its concentration varies in the same trends with the deposit size and the occurrence position.There exists a genetic relationship between hydrogeochemical characteristics of Cu²⁺ and copper deposit types and scale.So it provides a good hydrogeochemical signal for exploring this type of ore deposits.
