Abstract:<p>Geological-geochemical evidence points towards higher mantle potential temperature and a different type of tectonics, known as plume-lid tectonics, in the early Earth. In order to investigate tectono-magmatic processes associated with plume-lid tectonics and the formation of felsic TTG-like crust, we conduct a series of 3D high-resolution magmatic-thermomechanical models at elevated mantle temperature corresponding to Archean conditions. The numerical experiments show two distinct phases in co… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
