摘要
休宁白垩系红层盆地是晚侏罗纪初,早白垩纪末形成的断陷盆地。盆地形成以后接受白垩纪的红色沉积物,沉积总厚度为2350—3929m。在喜马拉雅运动中盆地抬升,在构造、沉积和外力作用下,形成了典型的红层地貌。
Xiuning Basin is a fault trough basin.It is situated in the southern part of Anhui Province, China.And its area is 560km2. The regin of the basin was a part of the Jiangnan old continent. During the late Jurassic-early Cretaceous Period, the basin was formed by fault along old fault lines (Proterozic Era) Red sediment was deposited in the basin during the Cretaceous Period and its thickness was 2350-3929m. During the Ximalaya Morement the basin was raised and it was accompanied with fault action. The geomorphological types of red stratum were formed by the tectonic morement, deposition and exogenic force.
