四川宁南骑骡沟铅锌矿区隐藻类碳酸盐岩的沉积环境与成矿意义

摘要

通过对四川宁南骑骡沟铅锌矿区震旦纪上统灯影组地层的剖面测制,对在剖面上所取样品进行的镜下光、薄片研究,得出该区的隐藻类碳酸盐岩沉积环境属于潮下低能带一潮间高能带.这些藻类通过生物化学等作用对该区的成矿起了很大的作用.%Based on the ningnan coutry of sichuan's Qiluogou Pb-Zn deposit, Sinian section(cc) group is profiled, studied polished sections and chips. The sedimentary environment of cryptomonas carbonate belong to subtidal and intertidal is find. These algae plays a large role through biochemistry effect in metallogenic.
