| 摘 要： | 河南省鲁山县背孜石墨矿床地处华北地台南缘灵宝-鲁山-舞阳石墨成矿带。矿区主要含矿岩石为太华群水底沟组片麻岩及大理岩。该区断裂构造较为发育,构造活动对矿体起到了一定的破坏作用,同时造成了本区石墨的局部富集。矿石类型主要为片麻岩型石墨矿,石墨呈晶质鳞片状。通过野外观察,室内矿石组分研究以及碳同位素分析认为该石墨矿床成因类型应为沉积变质矿床,并具有后期热液叠加富集特征,成矿物质来源主要为有机碳与无机碳两种类型,且不同含矿岩石中碳质来源具有差异性特征。

| Abstract: | Beizi mining area is a large deposit in Henan Province. This paper expounds in detail the geological features, scale and of quality orebody. The genetic type of this Graphite area is sedimentary metamorphic, and with the characteristics of late hydrothermal superimposed enrichment. Based on carbon isotope and serious field survey, we put forward the source of graphite in gneiss is organic, and the source of graphite in marble are both organic and inorganic. Therefore the source of carbon is difference in this area. |
