摘要 大别山东麓北段结晶基底中的二长花岗质岩石具长石应力支撑结构,早期高级变质作用条件下的韧性推覆以长石类矿物普遍晶质塑性变形和同构造重结晶作用为典型特征,晚期在发育糜棱岩的低级韧性剪切变形阶段处于脆性状态,在其内部和边缘形成了包括微角砾岩、假玄武玻璃、黑色超糜棱岩和熔结超碎裂岩等脆性断层岩石.二长花岗质岩石中不同类型韧性和脆性断层岩石的成因和构造联系,记录了大别地体的抬升冷却历史和不同阶段构造变动的性质.

Abstract: The adamellitic gneisses in the basement in northern segment of eastern Dabie Mountains were characterized by feldspars stress-suppporting framework in response with deformation. All feldspars in the rocks involved into an earlier high-grade ductile thrusting were sheared by crystal plasticity mechanism. The adamellitic gneisses were in brittle state during a late low-grade ductile shearing when various brittle fault rocks, including micro breccia, pseudotachylyte, black ultramylonite and sintered cataclasite, were formed within or on the rim of the adamellitic gneisses. Origin of the various ductile to brittle deformation rocks and their structural relationships recorded an uplift-related cooling history of the Dabie terrain and the deformation process in different stages.
