摘要
山东南墅石墨矿是在角闪岩相区域变质作用并叠加长英质混合岩化下形成的变质矿床。本文首次定量地研究了表征石墨晶体结构完善程度的两个要素,即石墨化程度(μ)和石墨菱面体多型(R_h)含量。在此基础上,进一步分析了它们与矿石类型、变质相的相关关系。石墨晶体结构的系统研究,将为石墨的工业利用、石墨新用途的开拓和石墨矿物学的研究提供有用的资料。
The Nanshu graphite deposit of Shandong Province is a metamorphic deposit formed as a result of amphibolite-facies regional metamorphism superimposed by felsic migmatization. In this paper the two major elements——graphitization (μ)and the content of graphite rhombohedral polymorph(R_h)have been studied for the first time on the quantitative basis. Furthermore, their correlations with ore type and metamorphic facies have also been analyzed. Systematic studies of the structure of graphite crystals will open up the industrial and other new applications of graphite and contribute a lot to the further mineralogical study of graphite.
