Abstract

The metamorphic core complex of Lebaquan is formed at multiple stage extensional structure system, and is characterized by a three-layer texture: crystalline basement, middle shear cover-layer and upper brittle cover-layer.And the three layers are divided by basement denudational fault and cover-layer denudational fault.The paper mainly deals with material formation, texture and typical tectonic style, and analyses the formation age and tectoncs background.
