摘要
区域变质型石墨矿床是我国主要的石墨矿床工业类型,数量多、储量大。该类型矿床主要分布在中朝准地台和扬子准地台以及吉黑、秦岭等褶皱系的隆起区,多产于前寒武纪的中、深变质岩系中,矿体多呈层状、似层状和透镜状产出。主要矿石类型为石墨片麻岩和石墨片岩。石墨的碳源主要为生物碳,属有机成因。
Regional metamorphic graphite deposit is China＇s major industrial graphite deposit types,large quantities and reserves. This type of deposit is mainly distributed in the Sino Korean and Yangtze paraplatform, uplift of Jihei and Qinling fold system, which prolifics in the Precambrian and the deep metamorphic rocks.The ore body mostly outputs at bedded, stratoid and lenticular .The main ore types are graphite gneisses and graphite schist.The sourse of graphite carbon mainly is biological carbon,which is organic origin.
