Applications of X-ray computed tomography in the Earth Sciences
X-ray computed tomography (CT) is a non-invasive imaging technique that allows the imaging of opaque objects in 3D. Thanks to its non-destructive character, ease of use and custom-tailored construction, CT has rapidly evolved into a powerful and versatile research technique that is widely applied in material research and process monitoring. Since petroleum industry first introduced the use of CT for the analysis of (petro)physical characteristics like porosity of oil-bearing sediments in cores, the application of CT rapidly developed. New advances in hardware and software allowed to visualize rock properties and structures in great analytical detail in a wide scale of resolutions from micro- to nanometer level. Constant developments in analysis software now permit quantification of (petro) physical properties of rocks and soils, visualization of fluid flow in porous materials, quantitative characterization of fossil remains, monitoring and quantitative analysis of rock deformation in geomechanical tests, etc. Combination with other (non-destructive) research techniques like X-ray fluorescence or especially designed technical add-ons provides additional information about mineralogical or mechanical properties. The latest developments in CT largely demonstrated its potential to visualize and quantify sedimentary processes in experimental set-ups, thus providing physical evidence for theoretical insights on sediment transport mechanisms. |This session warmly welcomes contributions that relate to the use of CT in the Earth Sciences in general, including papers on rock, soil and fossil properties and structures, as well as on the formation and deformation processes that sediments, rocks, soils and fossils undergo.
