摘　　要：笔者研究黄陵断穹核部鳞片石墨矿床中石墨的矿物学特征,分析石墨生成的世代与石墨片径的关系,指出寻找大鳞片石墨矿的方向。本区石墨有序化程度高、结晶完好,具有高中级区域变质的成因特点;石墨有3个矿物世代,分别形成于绿片岩相、角闪岩相及麻粒岩相;石墨片径随变质程度提高而增大。碳质沉积岩原岩的角闪岩相及麻粒岩相分布区是寻找大鳞片石墨的目标区。The authors studied the Mineralogical characteristics of crystalline flack graphites in Huangling faulted dome-shaped core and analyzed the relationship between graphites generations and diameters of graphites,indicating the target areas for prospecting larger crystalline flake graphite deposits.The graphites in this area have perfect ordering and crystallization,and generated in middle and high ranking metamorphism.The graphites have three mineral generations of greenschist,amphibolite and granulite facics.The diameters increase along with metamorphic grades.The target areas for prospecting large crystalline flake graphite deposits are where amphibolite and granulite facies of the carbonaceous original rocks exist.
