摘要
湖北省夷陵区石墨矿主要位于黄陵断穹北部、圈椅倘穹窿东翼。矿床赋存于上太古界—下元古界水月寺群黄良河组((Ar2-Pt1)h)区域变质岩系中。总结湖北省典型石墨矿区——三岔垭石墨矿区地质特征、矿体特征及变化规律,对含石墨地层、控矿构造等进行综合分析,指出矿床属于区域变质鳞片状晶质石墨类型,矿体有既定的赋存层位,呈似层状、透镜状产出,因后期断层及岩脉等破坏,致使矿体形态产状较复杂;结合后山寺、二郎庙、谭家河和东冲河等矿点,指出黄陵断穹北部,圈椅倘穹窿周沿,石墨矿资源找矿潜力较大。
Graphite deposit in Yiling District is located mainly in northern Huangling faulted dome,where the east wing of Quanyitang.The deposit is located on the upper Archean-Proterozoic Water Temple group Huang Lianghe group（（Ar2-Pt1）h） regional metamorphic rocks.This paper summarizes geological characteristics,ore characteristics and variation law of the typical Hubei graphite mine（Sanchaya of graphite mining area）,analyzes graphite-bearing stratum and ore-controlling structure,and points out that the deposit belongs to regional metamorphism flake crystalline graphite type.Ore bearing strata is stratoid and lenticular.Due to the late fault,dikes and other damage,the orebody shape is complex.Combining with ore spots of Houshansi,Erlangmiao,Tanjiahe and Dongchonghe,the authors point out the northern Huangling faulted dome,the Quanyitang week have huge prospecting potential of graphite.
