Chapter 3, Table T8. Whole-rock major and trace elements for basement rocks determined by ICP-AES, Hole 1203A.

Notes: LOI = loss on ignition at 1025 degrees 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.
