Abstract:

According to the study made on saturated hydrocarbon fractions of Tertiary browncoals that collected from Baize, Nanning and Hepu of Guangxi Province, the hydrocarbonsin the brown coals are immatured. It is proposed that the resin and wax of higher plant,especially bacteria, could form large amounts of immatured hydrocarbon in immaturesarge. This is considerably important for immature or lower mature hydrocarbon exploration in Tertiary coal measures in China’s coast areas and continental shelf.
