Metamorphic core complex and neighboring basins in Hongzhen, Anhui Province

According to the geophysical analyses of gravity and aeromagnetic anomalies and the characteristic studies of metamorphic core complex in Hongzhen,tectonic genesis models of the Huaining and Wangjiang Basins have been discussed.Basin formation is related to the deep thermal flow in lithosphere and the regional squeezing and uplifting of metamorphic core complex as well as the following extensional tectonic movement.
