Figure F33. 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, IF = inflated flows, SMF = sheet and massive flows, TZ = transition zone, and SI = sheeted intrusives. The values of Ba, 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%.
