摘　　要：黑龙江鸡西麻山区民主南山石墨矿位于佳木斯—兴凯(地块)Fe-Au-P-石墨-矽线石成矿带(Ⅲ-53)中部,为一沉积变质大型晶质石墨矿床。矿石量为2000多万t,矿物量为100多万t,固定碳平均品位为6.09%。赋矿层位为中-新元古界麻山岩群西麻山岩组和余庆岩组,分为上下2个含矿层,石墨矿体30条。通过全面分析民主南山石墨矿的矿床地质特征,总结其成矿规律,为在黑龙江东部佳木斯隆起麻山岩群西麻山岩组、余庆岩组寻找同类矿床提供参考。The Minzhu′nanshan graphite deposit in Mashan District of Jixi City is located in the middle of the Jiamusi-Xingkai(block)Fe-Au-P-graphite-sillimanite metallogenic belt(Ⅲ-53).It is a large sedimentary metamorphic crystalline graphite deposit.Its ore amount is more than 20 million tons,mineral amount more than 1 million tons,and average grade of fixed carbon 6.09%.Its ore bearing horizon is Ximashan and Yuqing rock formations of Meso-Neoproterozoic Mashan Rock Group.It is divided into upper and lower ore bearing beds and contains 30 graphite ore bodies.An overall analysis of the geological characteristics of the Minzhu′nanshan graphite deposit and a summary of its metallogenic regularities are of a guiding significance for finding similar deposits in the Ximashan and Yuqing rock formations of Mashan Rock Group in the Jiamusi Uplift of eastern Heilongjiang Province.
