吉林通化二密铜矿床地球化学异常特征及找矿模型建立

摘要

In this paper, the authors studied carefully geochemical distribution and anomaly characteristics of main ore-forming elements of Ermi copper deposit in Jilin Tonghua, determined the elements anomaly pattern of W, Sn, Sr, Cu, Pb, Zn, As and Ag, which has obvious prospecting indicator. Based on the metallogenic geological background and ore controlling factors of the deposit, the geological geochemical prospecting model for the deposit is established.%本文细地研究了吉林通化二密铜矿主要成矿元素的地球化学分布及异常特征，确定了W、Sn、Sr、Cu、Pb、Zn、As、Ag等具有明显找矿指示意义的元素异常模式。同时结合矿床的成矿地质背景和控矿因素，建立起矿床的地质-地球化学找矿模型。
