Abstract: It is the one of the most important source rocks for the Buqu marine carbonate rocks in North Qiangtang Basin, but some issues about oil and gas geochemistry are not clear because the lowly research. The biologicsource constitution, sedimentary environment and maturity of organic matter in the Jurassic carbonate rocks in North Qiangtang Basin is studied preliminarily by means of biomarker analysis technology combined with other geochemical data. The result reveals that the hydrocarbon source rock were developed in sedimentary environment, the organic source material is mainly lowgrade hydrobios mixed with highgrade plants. The source rocks have higher maturity, and possess favorable conditions to form gas and oil.
