摘要
石墨在国民经济中占有很重要的地位。在本世纪二十年代以后,国内外不少地质工作者对石墨作了大量的研究工作,积累了丰富的经验,但多数侧重于矿床地质、岩石学和采选工作,而对石墨矿物内在结构的特点则研究不多。本文主要着重于石墨矿物的测试研究,用数据对比的方法阐明石墨晶格结构的完整性和变质作用(圈岩变质相)之间的相互关系。研究表明:石墨化程度(U),石墨菱面体多型(Rh)的含量,放热峰的起始温度和石墨矿石变质程度的深浅成明显的线型关系。
Graphite plays an important role in national economy. Geologists all over the world have done a lot of work for it and accumnlated a wealth of experience since the 1920's. But most of them paid particular attention to mineral deposits, petrology and mining & separating studies. Relatively, they did not study enough on features of internal structure of. graphite itself. This paper mainly concentrates on the testing study of graphite. We attempt to expound the interrelation between completeness of latticestructure and metamorephic degree (metamorphic facies of adjoining rocks) by data correlation analysis. These parameters, degree of graphitization(U), content of graphite rhornbohedral polytype(Rh), beginning temperature of graphite exothemic peak, are clearly linear with metamorphic degree of graphite ores.
