Thermal Structure from Models of Mantle Convection with Surface Plates, Temperature-dependent and Radially Stratified Viscosity

Shijie Zhong, University of Colorado, Boulder

This animation shows the evolution of thermal structure within the mantle over a period of about 4 transit times (equivalent to ~200 Ma). The scale of thermal structure is controlled by surface plates. Downwelling sheets and upwellings plumes are the predominant structures. Thermal anomalies below spreading centers only extend to a depth of about 200 km.
