The basic principles of organic petrographical, organic geochemistry, sedimentology, sequence stratigraphy and the technology of micro-area and spectra analysis have been applied in the paper to study the Jurassic hydrocarbon source rock of the northern edge of Chaidamu basin. The paper reveals the features of the coal petrological, chemical composition and hydrocarbon generating mechanism of the coal bearing source rock in the studied area. It also gives the hydrocarbon generation models of different kerogen types of the area. The technology of 〓CNMR and TOFSIMS are used together to evaluate kerogen's capacity of hydrocarbon generation.
