Figure F55. Primitive mantle-normalized plots of Sites 1141 and 1142 basalts. A. Individual profiles for each sample analyzed are defined. Site 1141 samples are depicted by a dashed line, and those from Site 1142 by a solid line. B. Sites 1141 and 1142 basalts are compared with dredge samples from eastern and central Broken Ridge (reported by Mahoney et al., 1995). The dredge data for central and eastern Broken Ridge are defined by the shaded fields. C. Three individual dredge samples with compositions plotting outside the fields defined in B are plotted for comparison with Sites 1141 and 1142 basalts and the main fields for eastern and central Broken Ridge. Normalizing values are from Sun and McDonough (1989).
