Geochemical analyses of whole rock and tephra groundmass, and volatile content analysis of melt inclusions of hauyne and alkali feldspars from Rungwe Pumice eruption

The dataset includes major element concentrations of Rungwe Pumice (RP) melt inclusions, RP matrix glass, hauyne, and feldspars crystals obtained with EPMA analyses (IsTerre Grenoble, France). Additionally, whole rock traces and major element concentrations obtained with Q-ICP-MS and ICP-OES respectively (ULB Bruxelles, Belgium) are provided. Water concentrations in hauyne-hosted melt inclusions and water and CO2 in hauyne crystals were obtained with FTIR spectroscopy in transmitted light (ISTO Orleans, France).
