地球化学信息在推断地质构造系统中的应用——以吉林省中东部山区为例

Application of geochemical information to the inference of geological structure system——a case study of the mountainous areas in the Middle East of Jilin Province

本文应用吉林省中东部山区1/20万水系沉积物测量资料,选择39个元素(包括氧化物)进行因子分析处理,根据因子分析所释放出的元素地球化学信息,结合主成矿元素,伴生元素以及造岩元素异常的空间分布特征,经综合解译后进行地质体和断裂构造的推断。

This paper chooses 39 elements （including oxide） to process 1：200 000 stream sediment survey datas in the central-eastern mountain area of Jilin Province, according to the geochemical information from factor analysis, and add to spatial distribution characteristics of the main ore-forming elements, the accompanying elements and rock-forming elements, this paper infers geological bodies and faults after integrated interpretation.
