Controls on density stratification in the early mantle

Davies, Geoffrey

Description

Previous numerical models of convection in the hot early mantle, incorporating simulated subducted oceanic crust and some viscosity stratification, developed thermal and compositional stratification, with cooler, strongly depleted mantle above hotter, slightly enriched mantle. The robustness of these results is explored through variation of some important parameters. The stratification is minor at present mantle temperatures but stronger at higher mantle temperatures because mantle viscosities...[Show more]
