摘要
通过对区域成矿地质背景、晶质石墨矿成矿地质条件、含矿带分布等分析研究,总结了区内晶质石墨矿的成矿地质特征,并初步探讨了区内石墨矿的矿床成因及成矿模式。研究结果表明:石墨矿赋存于新太古界太华群水底沟组,矿床类型主要为区域变质型晶质石墨矿,含矿层分布受区域大型断裂和褶皱构造控制;矿体规模及矿石品位中等,石墨鳞片较大;矿化层具有“低阻—高极化”的地球物理特征。
Based on the analysis and study of the regional metallogenic geological background, the metallogenic geological conditions of crystalline graphite ore and the distribution of ore-bearing belt, the metallogenic geological characteristics of crystalline graphite ore in the area are summarized, and the genesis and metallogenic model of the graphite ore in the area are preliminarily discussed. The results show that the graphite deposit is located in Shuidigou formation of Taihua group, Neoarchean. The type of the deposit is mainly regional metamorphic crystalline graphite deposit. The distribution of ore bearing strata is controlled by regional large-scale faults and fold structures. The ore body size and ore grade are medium, and the graphite scale is large. The mineralized strata have the geophysical characteristics of “low resistance and high polarization”.
