Improving Mass Conservation With the Tracer Ratio Method: Application to Thermochemical Mantle Flows

Abstract Modeling the evolution of composition in a convecting mantle is difficult since the associated chemical diffusivity is very small. Consequently, compositional evolution is often modeled using the advection equation which is prone to overdiffusion and spurious oscillations unless special num...
