甘肃北山地区大葫芦山一带地球化学特征及其找矿意义
Geochemical characteristics of Dahulu mountainous region in Beishan Area and the significance for ore prospecting
摘要
Abstract
Geochemical characteristics, distribution of geochemical anomlies and the characteristics of the geochemical anomalies suggest that rock weathering and migration pattern of elements, aeolian sand have heavy influencee on micro-element distribution of river sediments. Each stratigraphic unit and magmatic body constitutes different ore-forming geochemical settings. In the working area are developed 3 synthetic anomlies with different element associations and the anomlies are divided into 2 types, i. e. the anomly controlled by both stratum and structure and the other by granitoids. The anomlies are varied in metallo-genesis, mineralization space and significance for ore prospecing.关键词
