Notes: Samples from igneous Unit I-1. FeO* = all iron calculated as FeO, Fe2O3 and FeO = originally analyzed concentrations. Loss on ignition (LOI) corrected for iron oxidation. Major element oxides, including LOI, have been normalized to 100%. Total = sum of oxides as originally analyzed. Mg# = Mg/(Mg + Fetotal). CIPW Hy = Cross, Iddings, Pirsson, and Washington normative content (all iron calculated as FeO) for hypersthene.
