克孜勒萨依铁铜金矿区微量元素地球化学特征分析

Analysis of trace elements' geochemical characteristics in the Kezelesayi Iron-Copper-Gold Ore District

微量元素作为独特的地球化学"示踪剂",其地球化学特征往往很好地保存了有关成矿物质来源及其形成时地质构造环境的信息.本文基于多元统计方法,对新疆青河县克孜勒萨依铁铜金矿区岩屑地球化学样品所含微量元素进行相关性分析、聚类分析和因子分析,以查明以Au为主的微量元素地球化学特征.研究结果显示,研究区Au和As这2种元素活动性强,分异程度高,利于富集成矿,指示研究区在下一步找矿中应以寻找Au金属矿为重点.

As a unique geochemistry “tracer”,the trace elements’geochemical characteristics have often well preserved the information about the ore -forming material sources and the geological tectonic environment. This paper,based on the multivariate statistical methods,includes correlation analysis,cluster analysis and factor analysis to identified geochemical characteristic of the trace elements.In order to identify the geochemical characteristic of the trace elements in which Au predominates,this paper adopts a serious study of geochemical samples contained trace elements in the Kezelesayi iron -copper -gold ore district.Results show that two elements,i.e.Au and As in the study area are very beneficial to enrich and mineralize,because of its strong activity and high degree of differentiation.It indicates that in the future prospecting we should focus on Au metal ores.
