Notes: LOI = loss on ignition at 1025°C for 4 hr. Mg# = MgO/(MgO + FeO), in molar percent, with FeO calculated (as 90% of total Fe). In all figures all major element data are renormalized to 100% to correct for variable LOI. Only a portion of this table appears here. The entire table is available in ASCII.
