摘要
嘉尔噶勒赛汉块状晶质石墨矿赋存于古生界石炭系浅变质岩系之煤系地层中,具层控性。含煤岩系是块状晶质石墨成矿的物质基础,是晶质石墨成矿的内部条件。实验证明石墨可以在碳质浓度很高和相当高的温度以及还原环境中形成。煤系地层中的煤层、含煤的变质板岩均可以为块状晶质石墨的矿源层。该区块状晶质石墨的矿物学特征、结构特征表明该区块状晶质石墨的石墨化程度较高。
The coal deposits of the galgareshan massive crystalline graphite are located in the coal strata of Paleozoic carboniferous strata. The coal-bearing rock series is the material base of massive crystalline graphite and is the inner condition of crystalline graphite. Experiments show that graphite can be formed in high carbon concentration and high temperature and reduction atmosphere. The coal seam and metamorphic SLATE in coal strata can be the source layer of massive crystalline graphite. The mineralogical and structural characteristics of massive crystalline graphite in this area indicate that the degree of graphitization is high.
