Although the possibilities of X-ray micro-CT are becoming better appreciated in earth science research, the demands on this technique are also approaching certain physical limitations. As such, there remains a lot of research to be done in order to solve all the technical problems that occur when higher demands are put on the technique. In this paper, a review of the principle, the advantages and limitations of X-ray CT itself are presented, together with an overview of some current applications of micro-CT in geosciences. One of the main advantages of this technique is the fact that it is a non-destructive characterization technique which allows 4D monitoring of internal structural changes at resolutions down to a few hundred nanometers. Limitations of this technique are the operator dependency for the 3D image analysis from the reconstructed data, the discretations effects and possible imaging artefacts. Driven by the technological and computational progress, the technique is continuously growing as an analysis tool in geosciences and is becoming one of the standard techniques, as is shown by the large and still increasing number of publications in this research area. It is foreseen that this number will continue to rise, and micro-CT will become an indispensable technique in the field of geosciences.

“…A crucial prerequisite for meaningful comparisons between model and measurement is that both are conducted on representative sample volumes. Sample sizes ranging from sub‐micrometers to a few centimeters are commonly used for XRCT (Cnudde & Boone, 2013; da Silva, 2018; Gelb et al., 2009; Landis & Keane, 2010; Zubair, 2012). Larger samples may be more representative of the investigated rock, but suffer from lower spatial resolution (Figure 1).…”

“…Additionally, the method has been ascribed the ability to capture pores and pore Figure 1. Sample size (diameter of the cylindrical core) versus resolution for X-ray computed micro-tomography (XRCT) and magnetic pore fabric (MPF) methods (XRCT modified from Cnudde & Boone, 2013;Cnudde et al, 2011;Gelb et al, 2009;Zubair, 2012). The MPF resolution is 10-20 nm for sample sizes ranging from 6 to 25.4 mm diameter (Almqvist et al, 2011;Esteban et al, 2006;Humbert et al, 2012;Parés et al, 2016;Robion et al, 2014).…”
