Focusing the main research goal on paleo-central uplift belt of northern Songliao basin,guided by the train of research thought of integrating geology and geophysics, and usingmultiple means and methods, this paper reveals the structural characters and the evolutionaryprocess of paleo-central uplift belt in different aspects, and also disclose the distribution statusof basement lithologies.

The northern one is called the Yimeng paleouplift, and the south-central one, the Central paleouplift.

To reveal the formation mechanism of the Carboniferous slender-waist-shaped central paleouplift in Ordos Basin,a series of stress-strain simulations were carried out,in which the basin was simplified into an isopachic,isotropic and elastic shell model and loaded with the NS trending extrusion.

The authors think that the central paleouplift in the Ordos basin was formed under the nearly E W lateral compressive stress produced by the collision and amalgamation of the Qilian trough and the Ordos basin in early Palaeozoic time.

The Process of Structure-sedimentary and Their Correlation of the Cambrian Peroid in the Central Uplift Belt, Tarim Basin;

Structural features of the central uplift belt have been investigated by basin analysis and accommodation zone theory,indicating that,uplift forming has been controlled by the second grade faults,local structure has been controlled and complicated by the third and forth grade faults,and oil-gas accumulation level has been controlled by the combination features of faults.
