摘要
Ulgoin Basin belongs to the Middle Cenozoic volcanic rock area outside of the Songliao Basin.Based on an analysis of the physical characteristics of rock strata and taking advantage of the gravity,magnetic survey and electrical method,the authors carried out comprehensive interpretation and determined the distribution and tectonic framework of Cretaceous Bayanhua Group and Jurassic morphology.It is pointed out that the Ulgoin rift basin has a good prospect in the prospecting for oil and gas resources.
