| 中文摘要: |
| 青桥河石墨矿位于秦岭褶皱带南部,马道复向斜中部偏南。矿区已发现石墨矿体露头17处,圈定大小矿体数十个。该矿床赋存于下元古界低庄沟岩组的一套碎屑岩-碳酸盐岩建造内,岩石普遍遭受中—深程度变质。赋矿岩性以黑云母斜长片麻岩、片状石英岩、大理岩为主。本文在对青桥河石墨矿区地质概况、矿床特征论述的基础上,对矿床成因及区域找矿前景进行了初步探讨。分析认为,该区石墨矿应为片岩区域变质型晶质石墨矿床,区域上在相同层位内找矿的潜力巨大。 |

| The Qingqiaohe graphite mine is located in the southern part of the Qinling Mountains fold belt of the central south of the Madao syncline,graphite ore outcrop has been found 17, the size of dozens of orebody delineation. The ore deposit occurs in a set of clastic rocks - carbonate rocks of Lower Proterozoic Dizhuanggou group, rocks generally suffer from moderate to deep metamorphism, ore lithology is mainly for biotite plagioclase gneiss, quartzite, marble.In this paper, based on the discussion of the geological survey and the characteristics of the deposit, the genesis of the deposit and the prospecting potential of the area are discussed. The analysis thinks, the graphite mine area is schist regional metamorphic crystalline graphite deposit, great potential for prospecting in the same horizon in the potential region. |
