大洋中脊所产生的岩石圈板块,最终会通过消减作用而消亡。岩石圈的连续消减使消减带产生不同规模的地形特征,并引起这些地形特征与向陆板块相碰撞和(或)增生。这个工作组的主要任务是:阐明汇聚板块边界的地球动力学过程,及其它对于全球构造
The lithospheric plate produced by mid-ocean ridges will eventually die out by abatement. The continuous depletion of the lithosphere causes subduction zones to produce topographical features of different scales and to cause these topographical features to collide and / or proliferate with the continental plate. The main tasks of this working group are: to elucidate the geodynamic processes that converge the boundaries of the plate, and other aspects of the global tectonics
