The Study on Tectonic Evolution History of Western Depression Belt in Bayanhot Basin

Liu, XF.(Jianghan Petroleum Insitute)  
This paper had made a quantitative study on tectonic subsidence history and tectonic extensional history of the western depression belt in Bayanhot Basin,and discussed its stages of tectonic evolution. The study shows the western depression belt is a extensional subsidence belt controlled by extension along NW-SE direction during Late Jurassic-quaternary. Late Jurassic-Early Cretaceous is a faulting period. Cenozoic is a sag period. The extensional mount and total subsidence mount during each period gradually decline from the northern section to the southern section. Faulting activity during Late Jurassic is most intense. During this period,The extensional mount and total subsidence mount are biggest. All of above characters are related to the activity of Bayanwula mountain fault. The western depression belt underwent four tectonic evolution stages:the stage of formation of crystalline basement,the stage of intensely uplift, the stage of faulting activity,the stage of sag activity.
