Early Martian tectonic evolution: A study through geological and geophysical perspectives

Our research is themed to understand Martian heat loss mechanism.We mimicked Hellas size giant impact, using iSALE-3D shock physics code and executed impact simulations and used the results to a time-dependent thermal convection of a fluid with an infinite Prandtl number and a temperature-dependent viscosity under the Boussinesq approximation in a cylinder.Observed results indicate that the generation of thermal gradient, resembling plume and are significant in terms of the morphological observations, in and around the Hellas region.We also estimated the age of the wrinkle ridges of Mars on a global scale and we observed a global compression in Hesperian time (Ruj and Kawai, submitted to Icarus, under review).Research on MoonIn order to understand the mantle evolution of the Moon, we are working on the landing site of the Chang’E 4 landing site (Von Karman crater). We have prepared a geological map (taking morphology and mineralogy into count) of the landing site region, and now we are working on the timing and type of volcanic material found in and around the landing site.
