Beschreibung:
This dataset includes results from U-series and Sr-Nd whole-rock isotope compositions of the last four explosive silicic eruptions from Ilopango caldera in El Salvador (TBJ, TB2, TB3, and TB4). Sr and Nd isotope ratios were measured with a Nu Instruments thermal ionization mass spectrometer (Nu-TIMS) at Departamento de Geología, Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE) in the state of Baja California (Mexico), whereas U and Th concentrations and isotopes were measured at University of Wyoming (UWYO) were measured by isotope dilution using a ThermoFisher Neptune ICP-MS multicollector.
