AB: The NSF-MARGINS funded Leg 7 of the Cook Expedition (2001) has produced abundant amount of samples and data. While these have been the subject of intended published and ongoing research, they have also been successfully applied to undergraduate education at the University of Delaware. Mineral and whole rock analyses have been incorporated into Earth Materials courses as portions of problem sets. Mineralogy students have used mineral compositional data to calculate solid-solution end-members, while Petrology students have calculated CIPW norms from whole rock and melt inclusion analyses. The large numbers of samples analyzed allow students to observe a variety of data and also be assigned individual data sets for calculations. Furthermore, the Cook 7 data and thin-sections have allowed students to examine a variety of arc and back-arc examples and in some cases observe genetic linkages. Utilization of the Cook 7 materials has not been limited to coursework; examination of basaltic lava dredged from Esmeralda Bank has formed the basis of an undergraduate research project. EPMA analyses of mineral phases were combined with petrographic work to unravel a complex crystallization history that involved co-precipitating phases and magma mingling. These examples reveal that after their use in pure research, data and samples produced from the MARGINS initiative can make significant contributions to the education of the next generation of geologists.
