| 摘 要： | It has been shown from petrologic,geochemical,trace element and REE evidence that the gran-ite intrusions at Sikongshan,Anhui Province,can be assigned to two distinct types which are radically different in age and origin.The Precambrian gneissic granited resulted from remelting of old continental crust while the Mesozoic granites were derived ,also through remelting,from low-Rb/Sr rocks at greater depths.Granite masses at Tiantangzhai and Zhoujiawan in the Dabieshan Mountains are also dicussed.

| Abstract: | It has been shown from petrologic, geochemical, trace element and REE evidence that the granite intrusions at Sikongshan,
Anhui Province, can be assigned to two distinct types which are radically different in age and origin. The Precambrian gneissic
granites resulted from remelting of old continental crust while the Mesozoic granites were derived, also through remelting,
from low-Rb /Sr rocks at greater depths. Granite masses at Tiantangzhai and Zhoujiawan in the Dabieshan Mountains are also
discussed.
