摘要
对我国西南同变质系列不同沉积环境和时代的３个地区煤的镜质体的对比研究，发现它们在光学、煤化学、工艺、有机地球化学性质等方面均有差异。其中同是晚二叠世但沉积环境不同的曲靖地区和水城、六枝地区煤的性质特别是结焦性较为接近，而四川中生代煤与它们相差甚远。时代差异比沉积环境引起的差异强烈的多。引起等变质煤镜质体性质差异的原因是多方面的，成煤泥炭沼泽的地球化学性质或是否受海水影响并不总是起控制作用。
ased on the comparative research of vitrinite in coals of three regions in Southwest China,which have thesame metamorphic series, various sedimental environment and age,it is found that they are different in the optical,chemical,technological,organo-geochemical properties and so on. Among them,the coals from Quiing district and Shuicheng and Liuzhidistrict,which are the same as Upper Permian coal but have different sedimental environment,have the simlarproperties,inparticular,the coking propety,whereas the Mesozoic coal of Sichuan differs a lot from them. The differences raised from various age are more stronger them those raised from various sedimental environment. There are many causes that could result inthe different vitrinite properties in isometamorphic coals,they are not always within the control of the geochemical property ofcoal-forming peat swamp or whether it affected by the sea water.
