title: Major element and volatile compositons of volcanic glasses and related datasets for paleobathymetry of the Samail & Troodos ophiolites

description: This archived dataset accompanies the article "<em>Paleobathymetry of submarine lavas in the Samail and Troodos ophiolites: insights from volatiles in glasses and implications for hydrothermal systems</em>" in the Journal of Geophysical Research: Solid Earth (Belgrano et al. 2021). Comprehensive details on the aquisition and selection of this data are given in the accompanying article. This dataset archive consists of a multi-sheet Excel file containing: (1) Newly measured major element and H<sub>2</sub>O (± CO<sub>2</sub>) compositions for volcanic glasses recovered from the Samail ophiolite, respectively determined by electron microprobe analysis (EMPA) and Fourier Transform infrared spectroscopy (FTIR). (2) The raw Beer-Lambert equation parameters as used to determine these H<sub>2</sub>O (± CO<sub>2</sub>) compositions. (3) The H<sub>2</sub>O (± CO<sub>2</sub>) compositions of volcanic glasses from the Troodos ophiolite reproduced from Woelki et al. (2020) together with newly calculated volatile saturation pressures and their depth equivalents. (4) A compilation of previously published volcanic glass data used to calibrate and test the paleobathymetric approach at the centre of the related publication. (5) A reference list for previously published data.
