Controlled by the paleostructural features,sources,paleoclimates,and water bodies,(fan) deltaic and salt lake depositional systems,as well as four patterns of salt-lake sedimentary fill(fault slope zones,slope break zones,salt lake density flows and southern ramp gypsic salt).

The calculation about the area of filling-in and excavation of canal cross section is the basic work in earth volrme of the canal designing.

Taking Bayantala transfer zone in Hailaer Basin as an example,this paper analyzes sedimentary filling features in structural transfer zone through paleotopography restore and summarizes its hydrocarbon distribution rules.

Fracturing dominated structural evolution and sedimentary filling in these subsags.

Meanwhile,characteristics of tectonic activity in different periodic rifting and their controlling on sedimentary filling were studied.
