山西省刁泉银矿床微量元素地球化学特征研究

CHARACTERISTICS OF MICRO-ELEMENT GEOCHEMISTRY IN DLAOQUAN SILVER DEPOSIT,SHANXI PROVINCE

本文根据区域地层、岩浆岩、构造中微量元素分布特征，水系沉积物地球化学异常，微量元素在矿区各地质体中的分布特征，垂向、水平分带特征，元素的相关性及因子分析，元素在成矿作用过程中的地球化学行为，结合地质特征，提出刁泉银矿外国找矿的水系沉积物指示元素组合和原生晕指示元素组合，划分了刁泉银矿床微量元素的垂向和水平分带序列，并对矿床的成因、物质来源有所指示。

This paper presents :Characteristicsofmicro-elementdistribution in regional stratigraphic units, structures , magmatic rocks; stream-sediment anomlies; micro-element distribution in various geological units, their vertical and horizontal zonation within the mine area; correlationof theelements and their factor analysis and geochemical behavior during metallogenic process。 All theresults, together with geological features can be used to pick out element association of river-sedi-ment anomlies and the association of primary halo for searching Ag ore outside the mine,toout- line veritical and horizontal element zonation sequencies and provide some information about genesis and ore material sources for the silver deposit。
