Basalts collected during drilling and diving programs on Serocki Volcano mostly fall within a limited compositional range, and are moderately evolved, normal MORBs with distinctive high MgO contents (averaging 7.60 wt%) and high A1203 concentrations (averaging 16.14 wt% in whole rock samples). However, samples recovered from within the central crater have lower Ti02 and FeO*/MgO, and higher MgO and Al2O3 concentrations, and are most similar to glasses recovered at Site 649 about 45 km to...
