Deccan Volcanic Province volatile data compilation

This is a supplementary file to the Journal of Volcanology and Geothermal Research review article on <i>Volatile Emissions from Deccan Volcanic Eruptions and their Effects on Climate across the K-Pg Boundary</i>. This document hosts the updated compilation of literature data on the volatile content of the Deccan Traps magmas (Capriolo et al., 2024; Callegaro et al., 2023; Choudhary et al., 2019; Hernandez Nava et al., 2021; Sano, 2001; Self et al., 2008). The melt inclusion analysis has been carried out using several techniques, including NanoSIMS, Raman Spectroscopy, EPMA and FTIR. The majority of the analysed inclusions preserved in olivine, plagioclase and clinopyroxene phenocrysts and glomerocrysts form different lava flows that erupted across the Cretaceous-Paleogene (K-Pg) boundary 66 million years ago were glassy (Hernandez Nava et al., 2021; Sano, 2001; Self et al., 2008), with some being partially rehomogenised (Choudhary et al., 2019). CO₂ concentration in the melt is also calculated using the CO₂ density in the vapour bubble using Raman Spectroscopy and bubble volume fraction in melt inclusions (Capriolo et al., 2024; Hernandez Nava et al., 2021). This spreadsheet further contains the formation-specific melt S and F content data calculated based on experimentally derived clinopyroxene-equilibrium melt partitioning (Callegaro et al., 2023). This dataset intends to highlight the gaps in our current knowledge of volatile content measurements in Deccan magmas across the K-Pg boundary.
