摘要
秦祁昆接合部的矿床类型复杂多样,成矿时代跨度大,成矿地质条件复杂,成矿作用具有多类型、多来源、多成因和多期成矿的特点。矿床主要成矿期为印支期、华力西期,期次为加里东期和前寒武期。滩间山群、晚三叠世为研究区主要赋矿地层。
The types of deposits in the juncture of Qinqi Kunlun are complex and diverse,the metallogenic epoch span is large,and the metallogenic geological conditions are complex.The main metallogenic periods of the deposit are Indosinian and Variscan,and the stages are Caledonian and Precambrian.Tanjianshan group and Late Triassic are the main ore bearing strata in the study area.
