摘要
云南晚震旦世陡山沱期地台型建造的海浸建造底部 ,富含碳质和黄铁矿的碳酸盐岩——黑层 ,其 Cu、Pb、Zn、Fe、Ag丰度高 ,是成矿有利层位。研究表明在其穹隆与短轴背斜的倾没部、澄江城北玉溪天宝厂、晋宁甸头、昆明砚台村、宜良大拉得等均为有前景的找矿区 ;
The carbonate rocks riched in carbon and pyrite i.e.black layers are located in the bottom of platform of late sinian period doushantuo Group in yunnan province, which are of high content of Cu,Pb,Zn,Fe and Ag, and are believed to be a favorable place of ore forming. On the basis of study, it has been reviewed that the regions of its domal uplift and short axis anticlinal pitsh, such as north chengjiang, jingning etc. are of ore potentiality and the black layers in northern west edge of Niushoushan uplift region are important belts of silver searching.
