Ratios of major cations in the terrestrial planets and chondrites. a Magnesium/Si versus Al/Si. b Abundances of reduced (metal and sulfide) and oxidized Fe normalized to Si. Data sources are as in Fig. 1 and Urey and Craig (1953). Red symbols identify the inner solar system, NC chondrites; see text for details. The Si-bearing core results in a Bulk Silicate Mercury that plots off scale at Al/Si (0.143) and Mg/Si (1.53)
