Seismic Evidence for Plume and Subducting Slab in West Yunnan, Southwestern China

Western Yunnan is located within a gigantic Tethys orogenic zone between Gondwana and Laurasia.Magmatic activity records of the associated Wilson orogenic cycle show that the causes of plate spreading in the region might have been related to sub-mantle plume.Tectonics,geophysics, sedimentary strata,tectonic evolution of the lithosphere and other research results indicate that there is geological evidence for mantle plume magmatic activities in West Yunnan.Tomography also supports the idea that there is a su...
