摘要
在研究栗山坝矿区大地构造背景、地层、岩浆岩、构造等地质特征基础上,分析了土壤地球化学参数特征及成矿元素的相关性,总结了元素分带的组合形式及迁移、富集规律,圈定了土壤地球化学异常晕,认为元素异常严格受北北西断裂向及经东西向断裂蚀变带及地层界线、热液活动、岩脉等因素联合控制。根据土壤异常特征与成矿地质条件圈定了找矿靶区,为该区下一步找矿工作提供有利的信息和找矿方向。
Based on the study of geological characteristics such as tectonic background, strata, magmatic rocks and structures in the Lishanba mining area, the characteristics of soil geochemical parameters and the correlation of ore-forming elements are analyzed, and the combination form, migration and enrichment law of elements are summarized. The anomalous halo of soil geochemistry is delineated, and it is considered that the element anomaly is strictly controlled by the alteration zone and stratigraphic boundary of NNW fault and through EW fault, hydrothermal activity, vein and other factors.According to the abnormal characteristics of soil and metallogenic geological conditions, the prospecting target area is delineated, which provides favorable information and prospecting direction for the next prospecting work in this area.
