IODP Proceedings, Volume 335
Site 1256, Table T7. Whole-rock major and trace element compositions of basalt, granoblastic dikes, and gabbros sampled during Expedition 335.

ICP = inductively coupled plasma–atomic emission spectroscopy. Fe2O3T = all Fe as Fe2O3. Mg# = cationic Mg/(Mg + Fe) ratio with all Fe as Fe2+, Ca# = cationic Ca/(Ca + Na). LOI = loss on ignition. ND = not determined. This table is available in ASCII and in Microsoft Excel format (see 103_T07.XLS in 103 in TABLES in “Supplementary material”).
