摘要
己被国内地质学界广为重视的黔西南地区微粒侵染型金矿,矿床的分布和富集严格受低角度断层控制。笔者从地壳内多层滑脱的观点出发,结合研究区的典型矿床实例,将该区域内不同矿区,不同控矿特征的金矿床,纳入地壳浅部多层滑脱构连的统一模式中进行讨论,并据此对深部原生矿产富集的有利部位进行了预测分析。本文的目的在于,通过黔西南地区地壳浅层构造的理论分析,为该区的金矿普查与勘探提供一条新的思路。
The gold ore deposits in Southwestern Guizhou have aroused the interest of many Chinese geologists.Their distribution and enrichment are strictly controlled by low angle faults.The authors,from the view- point of multi-layer detachments within the crust and combining with the examples of typical gold ores in this area,suggest that these gold ore deposits,located in different regions and having different geological cha- razters,can be concluded into an unified model of detachment within the crust.According to the suggestion,authors calculate the favorable location of gold ores enriched within the crust.This paper aims at pro- posing a new idea of gold ore surveying and exploration in southwestern Guizhou.
