茅排地区金水文地球化学特征及找矿效果

Hydrogeochemical Characteristics of Gold and Evaluation on Hydrogeochemical Prospecting Effect for Gold in Linchuan Maopai Area,Jiangxi Province

本文通过对临川茅排地区金水文地球化学调查，指出了该区金水文地球化学特征，总结了金水文地球化学找矿标志，并对其找矿效果进行了评价．研究表明：该区水中金含量变化较大，其异常分布与金矿具有很好的一致性；水中金与Ｃｌ－，Ｃｕ２＋Ｓ２Ｏ三种离子关系密切，它们在空间上的分布具有一定的相似性，可作为该区金水文地球化学找矿标志；应用金水文地球化学找矿方法预测金矿找矿远景区，不仅可行，而且十分有效．

This paper expounds the hydrogeochemital characteristics of gold,sums up the hydrogeochemical prospecting criteria of gold and evaluates its effect,through investigation in the experiment in Linchuan Maopai area. Studies indicate the variation of the golds concentraton in water is large and the anomalous distribution of gold in water is consistent with gold deposit.The gold is closely related to Cl-,Cu2+ and S2,and they are similar with each other in distribution in the space,which can serve as the criteria for ore prospecting.Applying the method of hydrogeochemcal prospecting for gold to prognosticate the gold prospect area is feasible and effective
