  1. Uranium, thorium and potassium masses in the BSE (i.e. actual lithosphere plus mantle reservoirs) for the ‘cosmochemical’, ‘geochemical’ and ‘geodynamical’ models adopted in the present study and taken from ref. 14. HPE masses for the BSE are calculated multiplying each HPE expected abundance by the BSE bulk mass of 4.035 × 1024 kg. The “cosmochemical” BSE abundances are taken from ref. 42 and based on the enstatite BSE model of ref. 51. The ‘geochemical’ BSE abundances are taken from ref. 1 with some minor corrections for the K abundances taken after ref. 45. Finally, the “geodynamical” BSE abundances are taken from ref. 42, which is based on67 estimates.
