Extended Data Fig. 1: Simplified model of conductive heat flow through IF in the lowermost mantle.
From: Links between large igneous province volcanism and subducted iron formations
(a): Model setup of IF and D″ mantle at the CMB. IF is taken as 50% Fe-oxides and 50% SiO2 by volume. (b): Model results showing the fraction of heat flow through the IF box for a range of IF thermal conductivities. The thermal conductivity of both D″ mantle and SiO2 in IF are taken to be 10 W m−1K−1 (ref. 2).
