Initial Reports Volume 192
Chapter 6, Table T8. Geochemical data for whole-rock samples analyzed by shipboard ICP-AES, Hole 1186A.

Notes: * = analyses conducted on unignited samples. Fe2O3T = total Fe expressed as Fe2O3. LOI = weight loss on ignition at 1100?C. Mg# = atomic Mg/(Mg + Fe+2). Mg# and CIPW norms were calculated assuming 12% of the total iron is Fe3+, which is equivalent to Fe2O3/(Fe2O3 + FeO) = 0.13, or Fe2O3/FeO = 0.15.
