Dynamics of continental accretion

WebWe will address the fundamental question of how strongly the action of weather and climate at Earth's surface can influence global tectonics. We aim to understand if the processes of erosion and sedimentation control the large-scale … WebJan 1, 2015 · Moresi et al. (2014) included an overriding plate in their models and undertook 3D simulations of buoyant micro-continental ribbon accretion and showed that subduction re-established behind the accreted ribbon via margin parallel migration of a highly arcuate trench and as a consequence the ribbon was embedded into the overriding plate.
