| 中文摘要: |
| 河南省西峡县尹家沟石墨矿矿石量达3274.35万t,矿物量183.22万t,属于大型石黑矿。该矿位于秦岭造山带东段,木家垭-内乡断裂与淅川断裂之间,区内地质构造复杂,岩浆活动频繁,成矿条件有利。通过对该石墨矿床研究区地质特征、矿床地质特征等综合研究,初步认为该矿床石墨中的碳主要来自有机碳,少数来自无机碳,矿床成因类型为沉积变质型矿床。这为西峡地区今后开展石墨矿矿床成矿规律研究及下一步地质找矿工作提供了科学依据。 |
| 英文摘要: |
| The Yinjiagou graphite mine in Xixia County, Henan Province is located in the eastern part of the Qinling Orogenic Belt, between the Mujiaya-Neixiang fault and the Xichuan fault. The geological structure in the area is complex, magmatic activity is frequent, and the mineralization conditions are favorable. In this paper, through comprehensive research on the geological characteristics and geological characteristics of the graphite deposit research area, the genesis of the deposit is preliminarily discussed. It is considered that the carbon in the graphite of the deposit mainly comes from organic carbon and a small amount comes from inorganic carbon. . These results provide a scientific basis for the future research on the ore-forming rules of graphite deposits in the Xixia region and the next geological prospecting work. |
