| 中文摘要: |
| 河南内乡县朱庙石墨矿床产出于下元古界秦岭群雁岭沟组中,岩性主要为大理岩,夹少量黑云斜长片麻岩等,下部岩石普遍含有石墨；石墨矿床的形成经历了沉积期、区域变质成矿期、岩浆热液叠加改造期和构造运动改造期。通过对矿床成矿地质条件、矿体特征等研究,总结出矿床成矿模式及找矿标志,认为朱庙石墨矿床为沉积变质+热液改造型叠加成因的晶质石墨矿床。 |
| 英文摘要: |
| Zhumiao graphite deposit in Neixiang County Henan Province is produced in lower Proterozoic Erathem of Yanling Formation Qinling group. The lithology is mainly marble, with a small amount of biotitic plagioclase gneiss, etc. The lower rocks generally contain graphite; The formation of graphite deposit has gone through the sedimentary period, regional metamorphic mineralization period, magmatic hydrothermal superimposed-reform transformation period and tectonic movement transformation period. By studying of metallogenic geological characteristics and ore body characteristics, comes to the conclusion of ore deposit metallogenic model and prospecting indicators. It is considered that zhumiao graphite deposit is a crystalline graphite deposit caused by sedimentary deterioration plus hydrothermal transformation. |
