摘要
根据有机岩石学方法研究了南桐矿区煤有机显微组分的特征。在显微镜下发现了大量与煤成烃有关的有机显微组分,如渗出体,变渗出体,各向异性微粒体,各向异性沥青质体,变木栓质体等。它们与该矿区煤层的高含烃性有着密切的成因关系,并且是高含烃性煤成烃的显微光学标志。
According to principles of organic petrology, the authors studied the characteristics of organic components in coal from Nantong Mine area. Under the microscope, a lot of organic components related with the coal-generated hydrocarbons are found, such as exsudatinite, meta-exsudatinite, aniso-micritinite, aniso-bituminite and meta-subermite, etc, which have close genetic relation with the high content of hydrocarbons in coal seams in this mine area and are the-micro-indicators for high-hydrocarbon coal.
