摘要
大陆深俯冲研究已经成为21世纪发展板块构造理论的前沿和核心课题.大别-苏鲁造山带出露有世界上最大的超高压变质构造单元,地球科学家以此作为天然实验室,在超高压变质和大陆碰撞的一些重要领域取得了国际上有影响力的系列成果.本文概括了其中12个方面的突出进展,主要包括超高压变质岩的空间分布范围、超高压变质作用的年龄、超高压变质作用的持续时间、深俯冲陆壳的原岩性质、大陆碰撞过程中的俯冲侵蚀和地壳拆离、大陆地壳俯冲的可能深度、大陆俯冲带深部流体活动、大陆碰撞过程中的部分熔融、大陆俯冲带深部元素活动性、俯冲大陆地壳物质再循环、碰撞后岩浆作用的地球动力学机制、碰撞造山带岩石圈结构等.对今后研究的问题和方向也提出了建议。
