WebChondrites have low concentrations of CaO. The ratio of CaO to Al2O3 varies greatly in terrestrial rocks. In contrast, in most meteorites, virtually all the Al2O3 and most of the CaO is carried by feldspar, so there is little variation in CaO/Al2O3. Among meteorites, MgO necessarily increases with Fe2O3(T) + MgO. greater boulder area
