Figure F45. Abundances of Ni, Sc, Sr, and CaO vs. MgO content for Detroit Seamount lavas. Solid lines connect the picritic lavas from Units 11 and 16 with other lavas from the same units. These lines show the effects of olivine accumulation. The unusually low incompatible element content of Site 884 lavas is obvious in the Sr panel. The CaO panel shows that the alkalic basalt from Site 1203 (Unit 23, 26, 29, and 30) extends to the highest MgO content and has relatively low CaO contents.
