Major and trace element analyses of volcanic rocks from the Galapagos Archipelago / Galapagos Islands
Harpp, Karen S
This dataset contains major and trace element analyses of volcanic rocks from the Galapagos Archipelago, selected from across the region to be representative of the geochemical variation in the hotspot system. The goal of the project is twofold: a) to assemble a dataset of radiogenic isotope ratios performed at a high and consistent level of precision; and b) to compare radiogenic isotope ratios with recent Hawaii isotopic signatures. To build a complete dataset, we selected the samples from across the archipelago from existing collections, in addition to new samples from Espanola, San Cristobal, and Santa Cruz Islands. Any samples that were missing published major and full suites of trace element data were also analyzed for those missing data. The samples analyzed at Colgate University for majors by XRF and for trace elements by ICP-MS are included here (i.e., new data).
