The tomographic images were acquired at a voxel-resolution of 5.2 µm and time-resolution of 33 minutes. The data were collected with lab based microCT, with an aim of investigating the influences of rock mineral and physical heterogeneity on dissolution patterns and changes to dynamic rock properties at the pore-scale. Further details of the experimental methodology can be found in Al-Khulaifi et al. (2019). These time-resolved tomographic images can be used to validate pore-scale multimineral reactive transport models. qccsrc@imperial.ac.uk Qatar Carbonates and Carbon Storage Research Centre United Kingdom not available pointOfContact Qingyang Lin Imperial College London London United Kingdom not available author Qingyang Lin Imperial College London London United Kingdom not available pointOfContact notApplicable https://resources.bgs.ac.uk/images/geonetworkThumbs/7f2e4f9e-708e-611b-e054-002128a47908.png Geology GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Tomography Carbon capture and storage Dissolution Porosity BGS Thesaurus of Geosciences 2022 revision NGDC Deposited Data UKCCS Citable Data dataCentre NERC_DDC otherRestrictions intellectualPropertyRights Either : (i) the dataset has not been formally approved by BGS for access and use by external clients under license; and / or (ii) the dataset contains 3rd party data or information obtained by BGS under terms and conditions that must be consulted before the dataset can be provided to, or accessed by, BGS staff or external clients.

(2019). The rock samples were imaged with bench top microCT Versa XRM-500 using a fan beam with photon energies of 50 keV for the initial dry scan of the rock samples and 100 keV for the subsequent wet scans where pore growth due to dissolution is captured. Tomographic images with a size of 20003 voxels were acquired, which were then binned (2×2×2) to obtain images of 10003 voxels with a voxel size of 5.2 ?m. Total acquisition time for each dynamic tomographic image was 33 minutes. The raw grey scale images where filtered using Avizo software NL-means filter (5 5 6), then segmented and processed using Avizo software and converted to The images enclosed are segmented image in 8 bit unsinged .raw format, containing three phases, pore space, dolomite phase and calcite phase.
