摘要:
当今板块构造理论的发展越发需要精细化研究, 前人在板内变形、洋中脊增生、裂谷拓展以及板块驱动力等方面开展了大量工作。但大洋岩石圈内部仍有很多微型构造块体没有得到更完善的认识和整理。本文总结前人关于裂谷拓展、洋中脊跃迁以及洋中脊?点相互作用的研究, 归纳全球跃生型微地块实例。结合大洋岩石圈内部微地块的形成和消亡过程, 提出了3个跃生型微地块演化模型, 即三节点重组模型、微陆块的大陆裂谷跃迁模型和微洋块的洋中脊跃迁模型, 并探讨其深部动力和物质来源, 便于进一步开拓洋中脊重组和海底构造的研究工作。大多数跃生型微地块是由于洋中脊?点相互作用导致的, 地幔柱对跃生型微地块的形成具有显著控制作用。跃生型微地块是深浅部构造耦合研究的关键。跃生型微地块可以由延生型微地块、残生型微地块等转化而来, 也可能在板块运动过程中转化为增生型微地块或碰生型微地块等。
Abstract:
Nowadays, the development of Plate Tectonics Theory needs more detailed research. Previous researchers have done a lot of work on intraplate deformation, rift propagation and ridge jumping. However, there are still many micro-blocks in oceanic lithospheres which are not well understood and studied. This paper summarizes the previous results on rift propagation, ridge jumping and ridge-plume interaction, and gives some examples of global ridge jumping-derived micro-blocks. Combined with the formation and extinction of micro-blocks in oceanic lithospheres, ridge jumping models of continental micro-blocks, oceanic micro-blocks and the triple junction reconstruction model have been proposed. The deep dynamic and material sources are discussed, which will facilitate the further study of ridge reconstruction and submarine tectonics. There are many factors triggering rift propagation and ridge jumping. Many micro-blocks are caused by ridge-plume interaction. The mantle plume has a significant control on the formation of micro-blocks. The ridge jumping-derived micro-blocks are a key to understand deep-shallow tectonics coupling. They can be transformed from the propagation-derived micro-blocks and the subduction-derived micro-blocks, and may also be transformed into the accretion-derived micro-blocks or the collision-derived micro-blocks in the process of plate evolution.
