摘　　要：塔儿坪石墨矿区地处北秦岭复合岛弧杂岩带东段,石墨矿赋存于古元古界雁岭沟岩组第二岩性段,为区域变质型矿床。矿石工业类型为石墨石英片岩和石墨大理岩,以大鳞片晶质石墨矿为主。通过对区内石墨矿体磷片大小的定量统计,结合变质作用机理,认为岩体侵位对石墨鳞片的增大起到了重要的促进作用。The Taerping graphite mine area is located in the eastern section of the north of Qinling Mountains complex island arc complex zone. The graphite ore is a regional metamorphic deposit which located in the second lithologic section of the Yanlinggou Formation in the Paleoproterozoic. The ore industry type is graphite quartz schist and graphite marble,mainly large scale crystalline graphite ore. By the quantitative statistics of the size of the graphite orebody in the area,the author considers that the emplacement of the rock mass has played an important role in promoting the increase of graphite scales.
