摘要: 湖北宜昌三岔垭晶质石墨矿床大地构造位于上扬子台坪黄陵断穹北部,是我国重要 的晶质石墨矿床之一。为进一步探究其矿床成因,通过矿床地质特征、石墨碳同位素特征、矿石 固定碳含量分析测试,可知矿体主要赋存在黄良河组地层中,矿石类型主要为含石墨片岩。石墨 矿石固定碳含量在14.75%~19.22%,大鳞片石墨占85%,小鳞片石墨占15%。石墨δ13C‰测试值 在-10.62‰~-11.69‰。推测三岔垭石墨矿石墨碳质主要来源有机碳,少量来源无机碳。

Abstract: The Sanchaya crystalline graphite deposit in Yichang,Hubei Province is located in the northern part of the Huangling fault dome in the upper Yangtze platform. It is one of the important crystal⁃ line graphite deposits in China. In order to further explore the genesis of the deposit,through the geological characteristics of the deposit,graphite carbon isotope characteristics,ore fixed carbon content analysis and testing,it can be seen that the ore body mainly occurs in the Huanglianghe Formation strata,and the ore type is mainly graphite schist. The fixed carbon content of graphite ore is 14.75%~19.22%,large flake graphite 85%,small flake graphite 15%. The test value of graphite δ13C‰ is -10.62‰~-11.69‰. It is speculated that the source of graphite carbon in Sanchaya graphite ore mainly comes from organic carbon and a small amount of inorganic carbon.
