Raman and fluid inclusion dataset of Zhongba, Zedang and Luobusa ophiolitic massifs, Yarlung Zangbo Suture Zone

This dataset supports the manuscript "Olivine-Hosted Fluid Inclusions Record Widespread Abiotic Hydrogen Generation and Preservation in Neo-Tethyan Forearc Mantle." It contains the Raman spectroscopic, hyperspectral Raman mapping, fluid-inclusion petrographic, and microthermometric data for olivine-hosted fluid inclusions in peridotites from the Zhongba, Zedang, and Luobusa ophiolitic massifs, Yarlung Zangbo Suture Zone, southern Tibet. Contents: Raw Raman and image data — raw Raman spectra together with photographs of the analyzed (spot) locations. Petrography images — plane-polarized and cross-polarized light photomicrographs of whole thin sections. Hyperspectral Raman mapping data — raw mapping data used to image the spatial distribution of H₂, CH₄, serpentine, brucite, and magnetite within individual inclusions. Microthermometry video — video recordings of vapor-bubble changes during heating runs.
