These are data pertaining to Wadsworth et al. (2022) which are published here: https://doi.org/10.1016/j.jvolgeores.2022.107672. How: Samples were set in epoxy and ground to the point where half of the glass chips collected were ground away. Then the sample was turned around and the other half of the particles were ground away until a thin slice of the chips remained at about 0.05 mm thick. At this point, the thin slices of volcanic chips were measured using Fourier Transform Infrared How: Spectroscopy (FTIR) at JAMSEC (Japan) by Iona McIntosh in collaboration with coauthors and Fabian Wadsworth. The data are the primary data in this manuscript. These data were collected to investigate how much water is remnant in particles that are known to have formed by the competition between degassing of H2O and sintering in volcanoes. That competition has implications for the development and destruction of permeability, which is at the core of this project.

This dataset consists of EBSD (electron backscatter diffraction), AMS (anisotropy of magnetic susceptibility) and AARM (anhysteretic anisotropy of remanent magnetisation) files, and magnetic carrier characterisation information, for samples collected from the Whin Sill ,northern England. Described in the paper Unravelling the complex record of magma flow and solidification in sills (Williams et al. 2025 - accepted into the Journal of the Geological Society May 2025). This work was completed at the University of Liverpool. Samples were collected and named WS01, WS02, WQC1C, WQC2C and WQC3C. The dataset includes .ctf files from the samples, which contain crystal orientation data from thin sections, .ran files which include the AMS and AARM fabric information for each sample, and .cur files of magnetic susceptibility data, hysteresis data from VFTB.
