From: Constraining composition and temperature variations in the mantle transition zone

a Global distribution of wadsleyite proportion. b Global distribution of the uncertainty of wadsleyite proportion. c Global distribution of ΔT. d Global distribution of the uncertainty of ΔT. e Global distribution of water content. f Global distribution of the uncertainty of water content. Deeply sourced hotspots10 are plotted as black triangles.
