Images and laser ablation ICPMS data for Fe-Ni-Cu sulfides from the Kohistan Arc, northern Pakistan (NERC Grant NE/P017312/1)

These files contain data for microscopy and mineral analyses on Fe-Ni-Cu sulfide minerals in the upper mantle and lower crust of the Kohistan arc system. Samples are dunites, harzburgites and pyroxenites with variable proportions of chromite from the Kohistan collection of Prof Brian Windley, that is held at Leicester University. Data were acquired during 2017 and 2018. Folders include: reflected light microscopy images of various sulfide minerals and mineral textures in thin section; maps and backscattered electron images of areas of thin sections; and metadata (time-resolved analysis spectral data) for laser ablation ICP-MS analysis of sulfide minerals. Laser-ablation ICPMS analyses were performed using a ESI UP213 laser system coupled to a Thermo iCAPRQ ICP-MS system at the School of Earth and Environmental Sciences, Cardiff University. The data were gathered to understand the concentrations of precious and semi-metal trace elements and their likely mineral forms in the various Fe-Ni-Cu sulfide minerals. Collected under the From Arc Magma to Ore System (FAMOS) Project.
