摘要
An 11.5 km long and 1 km wide ductile shear zone is developed in Zhajiadian-Yangmadianzi-Huiliushui area of Jianchang County,Western Liaoning Province.Based on field surveys,with petrofabric study and microscopic rotational strain analysis,the Yangmadianzi ductile shear zone is decided to be right-lateral shearing mechanism,with 1780 m shearing displacement.The ductile shear zone occurs in the granite of Neoarchean Majigou unit,which is covered unconformably by the accumulation of Mesoproterozoic Changcheng system,suggesting that the forming period of the ductile shear zone should be from late Neoarchean to Mesoproterozoic.
