摘要
通过分析河南省内的地层、构造、岩浆岩和变质作用等区域地质资料,研究晶质石墨成矿背景、成矿地质条件,对晶质石墨成矿带进行了划分。本文对四个石墨成矿带上典型石墨矿床进行剖析,确定大鳞片石墨分布在华北陆块南缘成矿带和北秦岭成矿带上,主要产于前寒武纪中深变质地区孔兹岩系中,赋矿地层分别为太华群水底沟岩组和秦岭群雁岭沟组地层,同时还总结了大鳞片石墨矿床成因,为研究区下步工作提供了理论依据。
By analyzing regional geological data such as strata,structures,magma rocks,and deterioration in Henan province,the crystal graphite-forming background and mineral geological conditions are studied,and the crystal graphite-forming zone is divided.Analyze the typical graphite mine on the four graphite mineral belts,and determine that the large scales graphite is distributed on the southern margin of the North China land and the northern Qinling Mining Belt.The layers of the ore ore are the layers of the Taihua Group Water Ditch Rock Group and the Yandinggou Group of the Qinling Group,which summarized the causes of large-scale graphite mines,and provided theoretical basis for the next work of the research zone.
