The extensional geodynamic setting of Early Cretaceous granitic intrusions in the eastern North China Craton: Evidence from laser ablation 40Ar/39 Ar dating of K-bearing minerals
|
Abstract:
Early Cretaceous Gudaoling batholith,distributed in the Liaodong Peninsula,eastern North China Craton,is composed by three types of grantoids,deformed diorite at Miaoling,gnessie granodiorite at Wanjialing,medium-grained monzogranite and enclave at Gudaoling.The diorite and granodiorites have evidently gnessis structures,indicating that they had experienced ductile deformation. The directions of foliations and lineations are accordant with those of host mylonites at the lower plate of a normal fault,suggest...
