Earthquake‐cycle deformation at subduction zones is not only induced by cyclical faulting processes but also impacted by the Earth structure and rheology. Oversimplifying the first‐order Earth structure in models leads to biased estimations of fault kinematics and Earth rheology and hence misinterpretation of subduction‐zone dynamics. Here we first...

The continental crust is unique to the Earth in the solar system, and controversies remain regarding its origin, accretion and reworking of continents. The plate tectonics theory has been significantly challenged in explaining the origin of Archean (especially pre-3.0 Ga) continents as they rarely preserve hallmarks of plate tectonics. In contrast,...

The timings of the onset of oceanic spreading, subduction and collision are crucial in plate reconstructions, but not always straightforward to resolve. The Paleo-Tethys evolution dominated the Paleozoic-Early Mesozoic tectonics of West Asia, but the timeline of events is still poorly constrained. We present new detrital zircon ages from the Binalu...

板块构造是指地球外壳岩石圈块体在地球表面的(水平)运动及其相互作用。自50年前板块构造理论建立以来,对板块运动的动力来源这一问题一直存在争议。早期的观点认为是“Bottom up”机制,即板块运动受控于板块之下的地幔对流系统,特别是起源于核幔边界的地幔柱作用于板块底部,促使大陆裂解,并驱动板块运动。而现今较为普遍接受的观点则是“Top down”机制,即认为板块运动的驱动力主要来源于板块自身的负浮力,板块构造和地幔对流均受控于板块的俯冲作用,因此板块构造又被称为俯冲构造。这一观点得到了众多地质和地球物理观测的支持。进一步研究表明,个别板块增速、减速与单一地幔柱活动在百万年时间尺度具有耦合关系;多个板块内稳定克拉通地区地表隆升、沉积速率与地幔柱相关的岩浆活动在亿年时间尺度存在时空相关性;而全球...
