Figure F27. Abundance of TiO2 vs. MgO showing that lavas from Detroit Seamount exhibit a wide range in TiO2 at a given MgO content. TiO2 abundance increases in the following order: Site 884 basalt < transitional and tholeiitic basalt from Site 1203 < Site 1204 basalt < alkalic basalt Units 23, 26, 29, and 30 from Site 1203. Note that three Site 883 lavas and the lavas from Unit 1 and Subunit 2a (except for the lowermost Subunit 2a sample) (Table T7, ) in Hole 1204B have <4 wt% MgO.
