Mass of Archean granite rocks and metamorphic layered sequence exposed in Chentaigou area of Anshan are typical for studying Archean crustal formation and evolution�� We systematically divide the rock units and analyse their rock fabric and structural deformation characteristics of the Archean rocks��with focusing on their compositions and structural features��in the Chentaigou area�� Fine-grained trondhjemitic mylonite��porphyritic granitic mylonite and medium-fine grained granitic gneiss have the characteristics of the Paleoarchean granitic rocks�� and underwent ductile deformation of middle-deep crust level�� Fine-grained trondhjemite is a product of the Mesoarchean magmatic events��showing impervious deformation and partial of ductile-brittle deformation fabric�� Metamorphic layered rocks of the Anshan Group mainly recorded the Neoarchean strong deformation event of middleshallow crust level�� The intrusion of the medium-coarse grained muscovite granite marked the end of early-phase different structural deformation processes in the Late Neoarchean�� The formation and evolution of the Archean crust in the Chentaigou area are also discussed��
