【摘要】 根据大别—苏鲁造山带浅变质岩系的地质产状，本文将其与高压—超高压岩石一起作为大陆板块俯冲的加积杂岩来考虑，发现它们在岩石类型、变质时代和原岩性质等方面具有一定的可比性，因此可看作为扬子板块大陆俯冲的加积杂岩。由此根据板块俯冲的加积楔模型，对浅变质岩系的形成和演化过程进行了地球动力学解释，结果对扬子板块俯冲及其与华北板块碰撞的俯冲带和缝合带位置提供了制约。更多还原

【Abstract】 According to the geological occurrences of low- grade and high to ultrahigh pressure metamorphic rocks in the Dabie- Sulu orogen,they can genetically be considered together as accretionary complex of plate subduction in the northern margin of the Yangtze craton,The low- and high- grade metamorphic rocks are comparable in their petrological types,metamorphic time and protolith nature and thus seen as the accretionary complex of the Yangtze plate subduction.In terms of the accretionary wedge model of plate subduction,the geodynamic processes of formation and evolution are explored for the different grades of metamorphic rocks in the Dabie- Sulu orogen.The results provide constraints on the tectonic locations of subduction and suture zones between the Yangtze and Sino- Korean plates.更多还原
