Initial Reports, Volume 197 Ms 197-105 Chapter 5, Table T8. Major and trace element concentrations in lavas from Nintoku Seamount, Hole 1205A. 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 these data are renormalized to 100% in order to correct for variable LOI. ND = not detected.
