Figure F30. Abundances of the incompatible elements Y, P, Sr, and Ba vs. Zr, a relatively immobile incompatible element. In each panel there is a general positive trend that mimics the trend defined by basalt from Suiko Seamount (M. Regelous et al., unpubl. data). There are, however, some important exceptions. In the P and Ba panels, some Site 883 lavas and the three labeled Hole 1204B samples deviate from positive trend to high P and Ba contents. Also, in the Y, Sr, and Ba panels the alkalic lavas from Site 1203 define nearly horizontal slopes, indicating that abundances of these elements are decoupled from Zr abundances.
