Research reveals the scale at which Earth’s mantle composition varies
A new study by geochemists from Brown University suggests that Earth’s mantle varies in composition over kilometer-sized pockets.
PROVIDENCE, R.I. [Brown University] — New research by Brown University geochemists provides new insights on the scale at which Earth’s mantle varies in chemical composition. The findings could help scientists better understand the mixing process of mantle convection, the slow churning that drives the movement of Earth’s tectonic plates. (more…)
