The deep part of Anda fault depression incluses Shahezi formation , Yingcheng formation and Denglouku formation.

The Beian fault is the most important fault in Beian area,it develops the Beianxi fault on it's west side,which tend towards is NNE,and spreads near "S" shape in the plane distributi.

Structural characteristics of deep fault depressions in the southeastern uplift area of the Songliao basin,China and their significance for petroleum exploration;

Characters of reverse tectonics and its forming mechanism in late of fault depression in Songliao basin.;

The fault depressions,isolated with one another but genetically related,are developed in deep of southern Songliao basin and most of them are considered to be capable of generating hydrocarbon.

This paper analyzes the gas reservoir formation condition of all the rifts in the north part of Songliao Basin, and proposes the apparent difference of hydrocarbon source rock development, organic matter evolution and cap rock condition among the rifts.

It determines that Xujiaweizi Rift is a complex rift controlled by two large fractures,i.

This paper discusses the effect of tectonics such as uplifting of the asthenosphere in the deep basin,the interaction between the crust and the mantle,the net structure,crust thinning and the detaching zone on the forming and evolving mechanism of the shallow rift and faults,providing.
