- Mengnan basin group is situated in the midwest of Inne r Mongolia.
- This is in accordance with the structural characteristics of lower Cretaceous and the thermal history of Jiuquan basin group.
这与酒西盆地及其周围地区 (酒泉盆地群 )下白垩统构造特征和盆地群热演化特征一致。
- In brief, in southern belt of southern north China basin group, volcanism and deposition have close relationships with tectonic activities in Dabie orogenic zone and Tanlu fault.
- Reservoir rock of Jurassic and lower Cretaceous in Beishan Basin group is mainly feldspathic litharenite and lithic arkose,Secondly is lithic sandstone,Both mineral and textural maturity are poor.
- In order to enlarge the field of oil and gas exploration and seek more resources, this paper analyzes the geodynamic condition and basin formation mechanics of Xinganling basin group.
- A number of suites of Carboniferous, middle-lower Jurassic and lower Cretaceous hydrocarbon source rocks were developed in the basin groups in the Paleo-Asian and Tethyan structural confluence area.
