Chapter 6, Table T5. Major and trace element compositions of mineral separates, Site 1271.

Notes: Only 19 mg of the 100-mg chromitite sample was dissolved. The high SiO2 content suggests that this sample also contained some silicate minerals in addition to chromite and other oxides. Mg# = 100 x (Mg/[Mg + Fe]) with all Fe as Fe2+. An = anorthite. NA = not analyzed, BDL = below detection limit. LOI = loss on ignition.
