吉林省中元古界老岭群花山组黑色岩系主要地质特征及其成矿作用

摘要

吉林省中元古界花山组中首次划分出典型的黑色岩系,有机碳平均0.74%,最高达15.4%,普遍含纳米级黄铁矿,在白山市杉松岗黑色岩系中,首次发现Pt、Pd矿,最高品位（0.1～0.145）×10-6。产在黑色岩系中的铜钴矿（大横路、杉松岗）是微生物作用、海底喷流作用、有机流体作用以及受后期热液改造的层控矿床。%The typical black rock series was divided in the Huashan Formation,mesoproterozoic in Jilin Province for the first time,organic carbon in an average of 0.74%,the highest 15.4%,Nano-containing pyrite.In Shansonggang Black Rock series in Baishan City,Pt and Pd were discovered for the first time,the highest grade（0.1-0.145）x10-6.copper and cobalt deposits in the black bock series（Dahenglu,Shansonggang） belong to late hydrothermal transformation of stratabound deposits by microorganisms,submarine jet effects,organic fluids.
