东海微板块的南北分块与水平运动
North-south segmentation and horizontal movementof the East China Sea micro-plate
【摘要】 前晚白垩世,闽浙-朝鲜二古沟-弧系和琉球沟-弧系组成古双俯冲带,东海微板块的构造运动受制于双俯冲带的作用.东海微板块基底和琉球岛弧的南北三分态势,是由于西侧二古为-弧系的不同区段对物质和应力的消减作用存在非均一性,从而在双俯冲带的作用下,导致东海地壳水平运动作差异性调整,而由此产生的NW向断裂分割的结果.
【Abstract】 Before Upper Cretaceous, the Paleo-Minzhe-the Paleo--Korea trench--arc system and the Ryukyu trench-arc system constitute the old double-subduction zone. The tectonic movement of the East China Sea micro-plate was subjected to the old double-subduction zone. The north south segmentation of the basement of the East China Sea and the Ryukyu trench-arc system,cutted by the NW-trending taults, is of different features in the each Part. Subduction of substance and stress was changed along the different zone of the western old double trench arc systems, such a double subduction zone accompanied differential adjustment of the crust horizontal stress with the NW-trending fauhs.
