Melt Inclusions in 2014 Tavurvur eruption products (Rabaul Caldera, Papua New Guinea)

This is the dataset for the journal article "Magmatic volatile budgets of the 2014 Tavurvur eruption at Rabaul Caldera, Papua New Guinea" published in Journal of Volcanology and Geothermal Research in July 2026 (DOI: 10.1016/j.jvolgeores.2026.108683) We analysed 84 plagioclase-, clinopyroxene- and olivine-hosted melt inclusions from 2014 Tavurvur volcanic bombs for major, trace and volatile elements (H2O, CO2, SO2, Cl, F) by EPMA, Raman, and SIMS and corrected them for post-entrapment crystallisation. File S1: Extended description of analytical conditions and precision and accuracy for the analytical methods used in this study, as well as supplementary figures. File S2: EPMA major element and SIMS volatile and trace element compositions of melt inclusions from the 2014 Tavurvur volcanic bombs. File S3: EPMA compositions of melt inclusion host minerals and matrix glasses from the 2014 Tavurvur volcanic bombs. File S4: Raman data for the 2014 Tavurvur melt inclusion shrinkage bubbles.本数据集对应2026年7月发表于《Journal of Volcanology and Geothermal Research》的期刊论文《Magmatic volatile budgets of the 2014 Tavurvur eruption at Rabaul Caldera, Papua New Guinea》（巴布亚新几内亚拉包尔破火山口2014年塔武武尔火山喷发的岩浆挥发分收支），DOI为10.1016/j.jvolgeores.2026.108683。 本研究通过电子探针显微分析（EPMA）、拉曼光谱（Raman）和二次离子质谱（SIMS），对2014年塔武武尔火山弹中84颗赋存于斜长石、单斜辉石及橄榄石中的熔体包裹体开展主量元素、微量元素及挥发分（H₂O、CO₂、SO₂、Cl、F）分析，并针对包裹体捕获后结晶作用进行校正。 文件S1：本研究所用分析方法的详细条件、分析精度与准确度说明，以及补充插图。 文件S2：2014年塔武武尔火山弹熔体包裹体的电子探针主量元素组成，以及二次离子质谱测得的挥发分与微量元素组成。 文件S3：2014年塔武武尔火山弹熔体包裹体寄主矿物及基质玻璃的电子探针组成。 文件S4：2014年塔武武尔火山熔体包裹体收缩气泡的拉曼光谱数据。
