黔东南地区热液型金矿的成矿作用及其模式

Metallogenesis of the Thermal-type Gold Deposit in Southeast Guizhou and Its Model

本文根据现有文献资料和笔者新近的观察研究,对黔东南地区热液型金矿的成矿作用及其构造控矿规律进行了探讨。尤其对大量分布的顺层石英脉型金矿,依其产状及结构构造特征划分为褶皱早期水平顺层充填含金石英脉和褶皱期及其期后倾斜“整合”充填含金石英脉两个基本类型,初步建立了区内热液型金矿的成矿模式,具有较大的找矿意义。

In accordance with data available for reference and recent investigation, the metallogenesis of thermal- type gold deposits in southeast Guizhou and its structure -controlling rules are made a discussion. Particularly, the bedding quartz -vein -type gold deposits in widespread distribution are separated from two basic kinds, including horizontal bedding -fining auriferous quartz veins at earlier phase of folding and inclined concordant- fining auriferous quartz veins at and after phase of folding, minerogenetic model for the thermal - type gold deposit is set up initially and has great significance of prospecting.
