| 中文摘要: |
| 呼热郭勒沟石墨矿区位于柴达木盆地南缘,东昆仑造山带西段。矿区出露地层主要为古元古界金水口岩群(Pt1J),该套地层原岩建造为一套陆源碎屑粘土岩—碳酸盐岩—基性火山岩沉积建造,沉积于浅海区。文章在列出区内地质矿产特征的基础上,结合国内针对石墨矿床成因类型的研究成果,认为呼热郭勒沟石墨矿床属受后期热液改造的区域沉积变质型石墨矿,具有较大的找矿潜力。文中在讨论石墨中碳质来源问题时,认同“石墨中的碳质来源于生物有机碳”的说法,并提出前寒武纪地层中的石墨矿,可以作为寒武纪时期局部地段远古生物尤其是微古植物发育繁盛的标志,可为地史、生命演化史提供佐证。 |
| 英文摘要: |
| The Hureguolegou graphite mine area is located in the southern margin of the Qaidam Basin and the western part of the eastern Kunlun orogenic belt. The outcropping strata in the mining area are mainly Paleoproterozoic Jinshuikou estuary group (Pt1J), which is a set of continental clastic clay rock-carbonate rock - basic volcanic rock sedimentary formation, which is deposited in shallow sea area.Based on the characteristics of geological and mineral resources in the area, combined with the research results of the genetic types of graphite deposits in China, it is considered that the Hureguolegou graphite deposit belongs to the regional sedimentary metamorphic type which is reformed by late hydrothermal transformation, and has great prospecting potential. In this paper, when discussing the source of carbon in graphite, we agree that the carbon in graphite comes from biological organic carbon, and for the first time put forward that a bold graphite deposit in Precambrian strata as the Cambrian period can be used as a symbol of the development and prosperity of ancient organisms, especially micropaleoplants, in parts of the Cambrian period, and can provide evidence for the history of geography and life evolution. |
