安徽洪镇变质核杂岩及其两侧盆地

摘要

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.%依据重力、航磁等地球物理信息和洪镇变质核杂岩及其周边地质特征研究,提出怀宁盆地、望江盆地构造成因机制,即盆地的形成与岩石圈深部热流作用有关,与变质核杂岩区域挤压隆升及其后续伸展滑覆构造运动有关.
