【摘要】 湖北省石墨矿属中国Ⅲ级成矿(区)带—上扬子中东部(坳褶带)Ⅲ-77-②湘鄂西-黔中南-磷-铝土矿-硫铁矿-石墨成矿亚带,文章对湖北省石墨矿产资源已知矿床的成矿规律进行分析研究。研究结果表明:湖北省主要出产晶质石墨,矿床类型主要以区域变质型为主;湖北省石墨矿主要赋存于前寒武纪地层中,代表层位为上太古界—下元古界水月寺(岩群),中元古界红安(岩)群和震旦系陡山沱组;湖北省鳞片状晶质石墨矿主要分布在宜昌、广水和红安等地;湖北省石墨矿矿石类型有片岩型、片麻岩型、变粒岩型、混合岩型、透辉岩型及大理岩型,其中,构成工业矿床的主要为大理岩型、片岩、片麻岩型,以大理岩型质量最好;湖北省隐晶质石墨矿主要分布在枣阳、随县、十堰,但品位较低,难以加工利用。更多还原

【Abstract】 Graphite mine in Hubei Province belongs to China’s grade Ⅲ metallogenic belt(zone)-middle and eastern Upper Yangtze(depression-fold belt) Ⅲ-77-② western Hunan and Hubei-central and southern Guizhou-phosphorus-bauxite-pyrite-graphite metallogenic sub-belt. Based on the analysis of metallogenic regularity of the graphite mineral resources in Hubei Province, the following conclusions can be drawn: the crystalline graphite is predominately produced in Hubei Province, and the main graphite deposit type is the regional metamorphism; the graphite ores mainly exist in the Precambrian strata with representative strata of Upper Archean-Lower Proterozoic Shuiyuesi Group, Middle Proterozoic Hong’an Group and Sinian Doushantuo Formation; flake crystalline graphite ores are predominately distributed in Yichang, Guangshui and Hong’an; graphite ore types include schist, gneiss, leptynite, migmatite, bistagite and marble; in these types of graphite ore, industrial deposits are mainly composed of marble, schist and gneiss, and the qualify of the marble one is the best; aphanitic graphite ores, which are difficult to process and utilize due to low grade of ores, are mainly distributed in Zaoyang, Suixian and Shiyan of Hubei Province.更多还原
