Abstract: As the important source rock layers in SunwuJiayin basin, Taipinglinchang Formation can be compared with Nenjiang Formation well that suffered the transgression. The analysis of major element, microelement and isotope indicate that the characters of high salinity and strong reduction at the bottom of Taipinglinchang Formation are in consistence with the characters of Nenjiang Formation. There is the upwardsdecreasing trend in salinity and reduction. In addition to the palaeoclimate and palaeobiology, it is believed that SunwuJiayin basin was the part of big Songliao basin in the early Cretaceous. Taipinglinchang Formation and Nenjiang Formation deposited in the same lake and suffered the transgression. The sedimentary circumstance of Taipinglinchang Formation is ideal for the organic matter accumulation and transferring to hydrocarbon in the source rock, which provide the material foundation of oil and gas generation.
