Initial Reports Volume 192
Chapter 3, Table 11. Geochemical data for whole-rock samples analyzed by shipboard ICP-AES, Hole 1183A.

Notes: All analyses were conducted on ignited samples. Fe2O3T = total Fe expressed as Fe2O3. LOI = weight loss on ignition at 1100degC. BD = below detection limit (0.01% is assumed for norm calculations). 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. - = not determined.
