Figure F15. East Pacific Rise (EPR) mid-ocean-ridge basalt (MORB)–normalized multielement plot of the average of different lithologic subdivisions from Hole 1256D. LP = lava pond, MF = massive flow, SF = sheet flow, BD = basalt dike, G1 = Gabbro 1, G2 = Gabbro 2. EPR values of Y, Sr, Zr, and TiO2 are taken from Su and Langmuir et al. (2003). Other elements are compiled from PETDB (www.petdb.org/) for basalts with MgO > 6.0 wt%.
