摘要
区域变质型石墨矿占我国石墨总资源储量的82%,是我国主要石墨矿石类型。区域变质型石墨矿主要分布在稳定陆块的隆起区,主要成矿带为华北陆块北缘石墨成矿带、佳木斯—兴凯地块石墨成矿带、华北陆块南缘及秦岭石墨成矿带、龙门山—大别山石墨成矿带、康滇隆起成矿带。主要成矿作用发生在前寒武纪,成矿时代越老,变质程度越深、石墨鳞片越大,开发利用价值越高,其中古元古代是区域变质型石墨主要成矿期。
The regional metamorphic graphite deposits are 82%of the total graphite resources in China,it’s the main types of graphite in China.Regional metamorphism type graphite ore are mainly distributed in stable continental uplift zone,and the main metallogenic belt is northern margin of north China landmass graphite metallogenic belt,Jiamusi-Xingkai block graphite metallogenic belt,the southern margin of north China landmass and graphite in Qinling metallogenic belt,the Longmen mountain-Dabie mountain graphite metallogenic belt,Kangdian ridge metallogenic belt.Mineralization mainly occurs in the Precambrian,the older the metallogenic epoch,the deeper the metamorphic grade,graphite flake,the greater the development and utilization of the higher the value,and palaeoproterozoic is the main metallogenic period of regional metamorphic graphite.
