摘要: 秦岭地区是我国石墨矿资源丰富的主要分布区之一，目前该地区石墨资源分布及成矿机理的研究尚较薄弱。以秦岭造山带已发现的数十处石墨矿床/点/远景区的基础资料为依据，通过典型矿床野外地质调查及测试分析，运用地质综合分析方法，研究结果表明：秦岭地区石墨资源分为晶质石墨矿床和隐晶质石墨矿床两大类，呈三大矿带展布。在秦岭地区多期构造运动叠加下，区域变质作用控制形成了鳞片晶质石墨矿床；在岩浆热力与构造应力双重作用下，煤、碳质泥页岩变质形成隐晶质石墨矿床。
Abstract: Qinling area is one of main repository distribution provinces of large scale graphite resource. At present, the research on the distribution and metallogenic mechanism of graphite resources in this area is still weak. Based on the basic material of dozens graphite deposits, spot, play discovered in Qinling orogen, by means of outdoors geologic survey and specimen examination with analysis of some typical deposits, applying geologic multidisciplinary analysis method. The results show that the graphite resources in Qinling area can be divided into crystalline graphite deposits and cryptocrystalline graphite deposits, which is distributed in three ore belts. Under the superposition of multiple tectonic movements in Qinling area, regional metamorphism controlled the formation of large scale crystalline graphite deposits. Under the dual action of magmatic heat and tectonic stress, coal and carbonaceous shale metamorphosed to form cryptocrystalline graphite deposit.
