摘要
西峡县军马河石墨矿属于秦岭—大别山褶皱系北秦岭朱阳关—柳泉铺石墨成矿带,矿区石墨矿赋存于秦岭群雁岭沟组地层中,含矿地层岩性为含石墨黑云斜长片麻岩、大理岩等,原始岩性组合为含碳砂泥岩和碳酸盐岩夹少量长英质、铁镁质火山岩,为一套有连续相序的浅海陆源碎屑—碳酸盐含炭沉积建造。矿床成因类型为沉积变质矿床,并具有后期热液叠加富集特征。区内石墨矿的控矿因素主要为原岩(建造)性质和变质作用[1]。矿床规模较大,估算资源量1 253万t,矿层厚度大且稳定,矿石质量好。
Graphite mine belonging to the Qinling-Dabie Mountains of North Qinling fold system Zhuyang off - Willow Shop graphite mineralization belt, graphite ore mining occurs in Qinling Goose Ridge Ditch group formation, rock formations containing ore of containing graphite gneiss, marble, etc., of the original lithology combination of carbonaceous shale and carbonate rocks interbedded sand a small felsic, mafic volcanic rocks, as a continuous phase sequence of shallow terrigenous-carbonate carbon-bearing sedimentary formations. Genesis of type sedimentary-metamorphic deposits, and has enriched the late hydrothermal superimposition characteristics. Graphite mine ore-controlling factors in the region are mainly original rock （construction） the nature and metamorphism. Larger deposits, estimate the amount of 12.53 million tons of resources, large and stable seam thickness, good quality ore.
