Abstract

Laboratory micro-CT scanning is a very useful tool in the characterization of geological samples. Due to its ability to visualize different phases and structures in 3D, many characteristics can be derived from the data. However, very limited chemical information on the different phases can be derived by CT. Micro-XRF (μXRF) images this compositional information for a wide range of samples. In μXRF, a 2D grid of fluorescence spectra is collected from the surface of the sample, generating 2D maps of the elemental composition of this surface. By extrapolating the gray values of the μCT data, this information is eventually known in the whole 3D structure.
