Dehydration of serpentine within a subduction zone setting causes the formation of pore space. The porosity and connectivity of the pores is important for fluid flux through these rocks. The pore space preserved within two recovered high-pressure and high-temperature multi-anvil samples was measured using µCT-scans at the BL20XU experimental hutch 2 of the SPring-8 synchrotron facility. The 3D images were obtained using X-rays with energy of 30 keV and by rotating the sample through 180° in steps of 0.1° (1800 projections) and an exposure time of 60 msec. The voxel size of the 3D images is 0.46 × 0.46 × 0.46 µm.
This repository contains sliced µCT-scan images (tif-format) for the two experiments (ES367 and V1167). Scans for each experiment are stored in separate folders. Continuous numbers for images are from data acquisition. Scans start and end in the sample, i.e. the subset used for pore space analyses does not include first and last scans because of air above and below the sample.
