New insights into the formation of Earth’s crust

A schematic summary of the effect of the convergence rate. Upper image shows a slow convergence rate allows thermal difussion and a derived reduction of slab's density (positive buoyancy). Lower image shows how a faster convergence rate increases the slab's density promoting the negative buoyancy. Credit: Kittiphon Boonma, Scientific Reports
