摘　　要：刘河甲石墨矿床位于沂沭断裂带东侧,胶北隆起区南缘与胶莱坳陷的衔接处,研究区构造较复杂,出露地层主要为古元古界荆山群陡崖组和野头组,区域成矿条件极好。本文基于区域地质背景特征及多年地质调查资料,通过野外地质调查、岩矿鉴定和岩石地球化学测试分析等手段综合研究,进一步查明了区内矿床地质特征和控矿规律等,系统总结了9个成矿要素特征,确定了研究区石墨矿床成因、成矿模式、找矿规律及找矿标志,对国内同类型石墨矿的找矿勘探工作具有重要的借鉴意义。The Liuhejia graphite mine is located on the eastern side of the Yishu Fault Zone,at the junction of the southern margin of the Jiaobei uplift and the Jiaolai depression.The study area has complex structural features,with exposed strata mainly consisting of the Jingshan and Yetou formations of the Paleoproterozoic Era,providing excellent mineralization conditions.Based on the regional geological background characteristics and geological survey,the geological characteristics and ore control laws of the deposit were further identified through field geological survey,rock ore identification,rock geochemical test and analysis.This article provides a comprehensive summary of the characteristics of nine ore-forming elements,as well as the genesis,mode of ore formation,prospecting rules,and indicators for graphite deposits in the study area.The findings are of significant reference value for the exploration of similar graphite deposits in China.
