FORMATION SETTINGS OF THE MESOZOIC AND CENOZOIC BASINS IN THE SOUTHERN PART OF NORTH CHINA

Formation and evolution of basins in the southern part of North China are mainly controlled by activities of the Qinling-Dabie orogenic belt and the Tanlu fracture belt. Based on analysis of volcanic tectonic settings generated in Mesozoic, regional tectonic evolution characteristics during the Indosinian and Yanshan epochs, and stress field, it is proposed that, the southern part of North China area has experienced compression, strike-slip, expansion and weak extrusion, resulting in the juxtaposition and superposition of basin prototypes.
