This paper using sedimentology, organic petrology and geochemistry studies the oil-related, Early and Middle Jurassic terrestrial coal measures, Junggar and Turpan-Hami Basins, NW China, shows that: (1) the oil generated in the main generating stage is earlier and generates from fluorescent desmocollinite (desmocollinite B), bituminite, cutinite and suberinite; (2) the oil-generating models of some individual macerals and oil expulsion experiment of vitrain sample are given; (3) the new organic petrological oil-source correlation techniques using laser-induced fluorescence, CLSM (Confocal Laser Scanning Microscope) and TEM (Transmission Electron Microscope) parameters for oil-source correlation are expressed and (4) the sedimentary organic facies will be founded by sedimentary, organic petrological and organic geochemical parameters, of which the running water swamp/marsh facies is best concerned with coal measures related oil.
