庾家河石墨矿产于秦岭群第二岩性段,通过1:5万的地质题图和化探扫面工作对该矿床的异常特征和成矿规律有了较好的认识,但对关系矿床后期扩大和开采的地质特征和成因存在许多不同的认识,通过野外填图钻探结合室内化学分析测试和岩矿鉴定等手段,分析得出该矿的主要含矿岩石为大理岩、黑云斜长片麻岩及云母石英片岩,矿体呈层状、似层状,产状与地层产状基本一致。矿区经历了沉积-聚炭和区域变质-结晶2个主要成矿期,矿床成因属区域变质型晶质石墨矿床。
The Qijiahe graphite mineral has a good understanding of the anomaly characteristics and metallogenic regularity of this deposit through the 1: 50000 geological map and geochemical exploration of the surface of the second lithologic section of the Qinling Group. However, There are many different understandings on the geological characteristics and causes of the mining. Through field mapping drilling combined with indoor chemical analysis and testing and identification of rock and mine, it is concluded that the main ore-bearing rocks in this mine are marble, Rock and mica quartz schist, the ore body is stratified, like stratification, occurrence and strata are basically the same. The deposit undergoes two major metallogenic stages of sedimentary-polymetallic and regional metamorphism-crystallization. The deposit belongs to the regional metamorphic crystalline graphite deposit.
