Abstract: Hydrocarbon-generated potentials of Middle-lower Jurassic coal measures in Junggar basin were discussed on the basic of geologic and geochemical analyses of conditions for coal-formed hydrocarbons in Gips and basin, Australia,and sources correlations were made among the discovered Jurassic oilfields. It is concluded that Middte-lower Jurassiccoaly successions were considered to be unfavorable for hydrocarbon generatio n terms of both the characteristics of geologic evolution macroscopically and compositions of kerogen macerals microscopically, and hydrocarbons from Jurassic oilfields in Jungar basin primarily related to Lower Jurassic humic-prone to humic Dispersed org nicatters (relam stone).

Key words: Junggar basin, Jurassic, Coal-formed hydrocarbon, Melamnudstone, Source rock
