酒东盆地营尔凹陷早白垩世断陷形成机制探讨
Exploring to rifting mechanism of the Yinger depression during the Early Cretaceous in the Jiudong Basin
摘要
Abstract
The Jiudong Basin, situated in the triangular belt between the Tibetan Plateau (TP) and the North China Plate(NCP) ,is one classical rift basin,but there is controversy for the mechanism of rifting during the Early Cretaceous. Because there are obvious differences for the tectonic forces between the two tectonic belts: N-S compressive stress of TP and NW-SE extension of NCP, it is so different to truly understand which tectonic force the formation of the Jiudong Basin was controlled in during the Early Cretaceous. So this study chooses the Yinger depression of the Jiudong Basin, which is far away strong tectonic Altyn Tagh Fault ( ATF) and has been studied by more geologists, to analysis the process of rifting formation using multiple methods, including mapping and correlation of 2D seismic reflection data, transition of sedimentary center,and ZTR values of sedimentary heavy minerals. All data indicate that rifting of the Yinger depression began to be active because the Jurassic normal faults were active due to the N-S extrusion of TP.the Early Cretaceous. And the formation process is divided into three stages: Initial, strong, atrophy rifting.关键词
