四道沟金矿地质控矿因素地球化学统计分析

Geochemical Statistical Analysis for Geological Controlling Factors of Mineralization of Sidaogou Gold Mine

以辽宁四道沟金矿区的部分有代表性地质样品分析结果为依据．通过多元统计分析．结合地质观察对矿区地质控矿因素进行了分析；得出了不同层次地球化学背景场的演化有利于金矿的形成．不同岩性、岩脉对金的成矿有一定的选择性但不具专属性，以及韧性剪切带不是控矿的主要构造等结论．

Multicomponent statistical analysis was carried out for the geological controlling factors of mineralizationof Sidaogou Gold Mine. Liaoning Province. based on the analytic results of a part of typical geologic samples in combination with geologic observation. It was concluded that the evolution against the geochemical background of different horizons are favorable to the mineralization of the gold deposit; lithologic features and veins will not provide the Particularityfor gold mineralization though they were available to offer selectivity in general;the ductile shear belt was not the predominant controlling structure for the mineralization of the gold deposit.
