辽宁四道沟金矿地球化学基本特征研究

四道沟金矿床的矿脉群规模较大且复杂，单个矿体较零碎，连续性不好。各矿体及矿化体的成晕相互干扰较大。通过对典型矿脉群中的矿体、蚀变带、围岩及构造带、预测点系统取样分析，据热液成矿成晕原理对矿区基本地球化学参数进行了多元统计分析的若干方法处理得出并分析了元素组合规律；确定了成矿指示元素并解释了指示元素的地质地球化学意义；总结了矿脉群中矿体原生晕中元素的轴向组合分带序列。

STUDIES ON THE BASIC GEOCHEMICAL FEATURES OF SIDAOGOU GOLD DEPOSIT IN LIAONING

In Sidaogu Gold Deposit,the scale of lode group is larger and more complex ,which thesingle orebody is scattered and poor-continuous,every orebodies or holoes of mineralizationbodies is greatly interfered each other. Through the systematic sampling analysis on ore-boies ,alteration zones,wall rock,structure belte and prediction sites in typical lode group andaccording to the ore-forming and holo-forming mechanism in hydrothermal process ,the paperanalysed the fundamental geochemical parameteres of Sidaogou Gold Deposit by multivariantstatiscal method,concluded the element association rules,determined the guide elements,in-terpretted the geochemical significance of the guid elements and sumarized the axial zone se-qence of guide elements from primary holoes of lode group.
