Solid (left) and elemental mass fractions (right) of solid planetary building blocks formed completely interior to the water ice line (T > 150 K) around a star with [Fe/H] = +0.2 (top) and [Fe/H] = +0.4 (bottom). As for [Fe/H] = 0 (Fig. 2), the solid composition is dominated by Mg2SiO4 and MgSiO3, while the elemental composition is dominated by oxygen and iron, making up around 60% of the total mass of the planet, as for all [Fe/H] values.
