The latest webpage to be posted, "Late Miocene fish fossils in Utah support accelerated extension and subsidence, not thermal uplift or a continental divide in the Eastern Snake River Plain", is an elegant and unusual demonstration that paleontology can contribute to the mantle plumes debate. It is interesting to reflect that paleontology also played a key role in the continental drift debate led by Wegener. –Gillian Foulger
Dear WM, He & Santosh (2020) constructed a regional teleseismic P-wave tomography model for 50-800 km depths in the east Tibetan Plateau and central China using 3D ray tracing/ To the extrusion style generated by collision, the direction changed from eastward to southeastward because of an obstacle of strong lithosphere identified by fast anomalies in the new tomographic image. They proposed that the Emeishan large igneous province was formed by a subducted slab-like high velocity anomaly at depths of 300-700 km and argued it was not generated by mantle plume.–Junjiang Zhu
