Abstract

Abstract

The convergence belt between the Sino-Korea block and the Yangtze block was strongly deformed by intracontinental tectonomagmatic activity in the Late Mesozoic.In order to show details of the belt during the Late Mesozoic, we have carried out a series of analysis for the Erlangping Group on mesosmall structure, micro-texture, electron-probe and geochronology.The study has recognized a ductile right lateral slipping deformation for the Xiaozhai-Erlangping shear zone inside the Erlangping Group, and a superimposion of ductile right lateral slipping and late brittle-ductile thrusting for the Damiao-Wantan shear zone.⁴⁰Ar/³⁹Ar tectonic-thermal chronological analysis reveals a continuous uplifting-denudating course between ~ 121 Ma and ~ 100 Ma.During the Late Mesozoic, the Erlangping Group experienced the tectonic reworkings respectively under the extensional, slipping and contractional tectonic regimes. Firstly, under the regionally extensional condition, the Erlangping Group was split by the XiaozhaiErlangping and Damiao-Wantan shear zones into three slabs, namely the Baoshuping, Huoshenmiao, and Erjingou slabs.Then in Early Cretaceous a right lateral movement of the slabs happened under a slipping regime.The intrusion of the Erlangping rock body ended the Xiaozhai-Erlangping shear zone, and the Damiao-Wantan shear zone was stopped under a contractional tectonic regime, which made the Erlangping Group welded into a single block again.Our results also indicated that the tectonic evolution of the Erlangping Group of the North Qinling in the Late Mesozoic processed in an opposite way to that of the Dabieshan tectonic belt.
