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).

本数据集涵盖隆古火山浮石（Rungwe Pumice，简称RP）熔体包裹体、RP基质玻璃、钙铝黄长石（hauyne）及长石晶体的主量元素浓度数据，上述数据通过电子探针显微分析（Electron Probe Micro Analyzer, EPMA）完成测试，测试机构为法国格勒诺布尔IsTerre实验室。此外，数据集还提供了分别通过四极杆电感耦合等离子体质谱（Quadrupole Inductively Coupled Plasma Mass Spectrometry, Q-ICP-MS）与电感耦合等离子体发射光谱（Inductively Coupled Plasma Optical Emission Spectrometry, ICP-OES）测得的全岩微量元素与主量元素浓度数据，测试机构为比利时布鲁塞尔ULB实验室。钙铝黄长石宿主熔体包裹体中的水浓度，以及钙铝黄长石晶体中的水与二氧化碳浓度，则通过透射光模式下的傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy, FTIR）测得，测试机构为法国奥尔良ISTO实验室。
