Abstract:The Western Liaoning and its adjacent areas, tectonically belonging to the inland area of the outer circum-Pacific tectonic belt, are developed with a lot of Mesozoic basins. According to the distribution of pre-Late Triassic basement, 61 basins are recognized. Based on their structural types, the basins are classified into four types, which are the depression-splitting basins, the splitting basins, the fault basins and the fault-depression basins. The depression-splitting basins were formed in Late Triassic-Middle Jurassic, and are therefore called the Early Mesozoic basins as well. The fault basins and^splitting basins, formed from Late Jurassic to the early stage of Early Cretaceous, are also called the early Late Mesozoic basins. The fault-depression type, known as the later Late Mesozoic basin, was formed between later Early Cretaceous and Late Cretaceous. The depression-splitting basins are related to the uplift and depression of paleoplate tectonics, but not to the thermal-tectonic system of the circum-Pacific deep-seated faults. The fault basins and splitting basins are closely related to the thermal-tectonic system of the circum-Pacific deep-seated faults, which strictly control the basins by the Daxinganling and Lower Liaohe-Shuangliao thermal-tectonic mole belts. The fault-depression type has a relation to the thermal-tectonic system located in the circum-Pacific rear-arc extension region.
