Micro-CT scan of a 4 mm diameter Belgian fieldstone (glauconite-rich sandstone) sample acquired with the HECTOR micro-CT scanner at Ghent University's Centre for X-ray Tomography (UGCT). 2400 projections were acquired with an exposure time of 1s each. The X-ray tube settings: 100 kV, 10W. The sample had a porosity of 18.16%. It consists out of quartz (low grey values) and glauconite (high grey values). Pore network model and lattice-Boltzmann simulations on this image were compared to minipermeameter and capillary absorption measurements by De Boever et al. 2016.
