An analytical curves between unit cell volume of bridgmanite and chemical substitutions (a) by iron and (b) by aluminum. The solid (red) circles are the present results. The dotted lines were fitted to literature values shown by open cirlces19,20,21,24,25,26,27,28,29,30,31,32,41,42,43,44,45,46,47,48,49,50,51,52,53. (a) 11.741x + 162.5 and (b) 12.926x + 162.5, where x is (Fe + Al)/(Mg + Fe + Si + Al) and V at x = 0 is fixed to 162.5 Å3.
