地球内部地幔的黏性对地球的热演化、地幔柱的上涌、俯冲大洋岩石圈的下沉以及不同化学组成物质在地幔内部的混合等有显著的影响。准确的查明地幔内部黏性的变化对于理解地球深部过程具有非常重要的意义。12月11日出版的《Science》上美国波特兰州立大学的Maxwell L.Rudolph等人对地幔黏性的研究成果。他们基于长波长 The cohesiveness of the Earth’s interior mantle has a significant effect on the thermal evolution of the Earth, the upwelling of the mantle plume, the subduction of the oceanic lithosphere and the mixing of different chemical composition within the mantle. Accurately ascertaining the change of the internal viscosity of the mantle is very important for understanding the deep process of the earth.
