| 中文摘要: |
| 石墨是生产石墨烯重要原料之一，其经济优越性和战略矿产资源地位显著，已成为多个国家的战略性关键矿产。龙首山成矿带红石泉地区最近发现的晶质石墨矿床具有较大找矿潜力，为进一步调查红石泉地区晶质石墨矿地质特征，采取“地质调查+激电测量+工程揭露”三位一体勘查手段，将地表露头与岩心编录成果相结合，发现矿体主要呈近东西向展布，产状为北倾，呈层状或似层状，主要赋矿岩性为古元古界龙首山群塌马子沟组灰黑色含石墨石英片岩，属于区域沉积变质成因。塌马子沟组石墨矿体顶部的一套灰绿色石英片岩是间接找矿标志，灰黑色石英片岩既是有利围岩又是区内重要的直接找矿标志，且赋矿石英片岩具有低电阻率和高极化率的特征，是重要的物探标志。综合分析地质物探异常特征，认为研究区矿体北西及南东向延伸与物探异常叠合区域及深部具有较大的找矿前景。 |

| As one of the important raw materials for the production of graphene, graphite has become a strate-gic key mineral in many countries because of its significant economic superiority and strategic mineral resources.The recently discovered crystalline graphite deposit in Hongshiquan area of Longshoushan metallogenic belt hasgreat prospecting potential. In order to further investigate the geological characteristics of the crystalline graphite de-posit in Hongshiquan area, the three-part exploration method of "geological survey + induced current survey + engi-neering exposure" was adopted, combining the results of outcrop and core cataloguing, and it was found that the orebody was mainly distributed in near east-west direction, and the occurrence was northward. It is stratified or strati-fied, and the main ore-bearing lithology is the graying black graphitic quartz schist of the Tamazigou Formation inthe Paleoproterozoic Longshoushan Group, which belongs to the regional sedimentary metamorphism. A set of grain-green quartz schist at the top of the graphite orebody of the Tamazigou Formation is an indirect prospecting indica-tor, grain-black quartz schist is not only the favorable surrounding rock but also an important direct prospecting in-dicator in the area, and ore-bearing British schist is an important geophysical prospecting indicator with low resis-tivity and high polarization. Based on the comprehensive analysis of geological geophysical anomaly characteristics,it is concluded that the north-west and south-east extension of orebody and superposition area of geophysicalanomaly in the study area have great prospecting prospect. |
