Abstract: The petroleum exploration degree of Tarim Basin is low, and the distinguished character and distribution of Lower Paleozoic source rock is still an important problem puzzling the geologist. By systematic analyses of drilled Cambrian source rock, geochemical character of Cambrian source rock was deeply studied.The result shows that owing to the difference of Cambrian depositional environment, the abundance of organic matter, the distribution of sterane and terpane and relative composition of dibenzothiophene, dibenzofuran, fluorine were varied apparently, and these parameters should be taken into account in oilsource correlation. As a whole, distinguished character of Cambrian source rock mainly include higher content of C28 in sterane, higher content of Gammacerane, and heavier carbon isotope ratios. The distribution of triaromatic hydrocarbon in Cambrian source rock is also different to Upper Ordovician source rock apparently.
