摘要

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 Clung 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 Ryūkyū trench-arc system,cutted by the NW-trending faults, 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 faults.
