Combination of Laboratory Micro‐CT and Micro‐XRF on Geological Objects
X‐ray micro‐CT is a very powerful tool for structural analysis of geological samples, but gives very little information on the chemical composition of the different structures visible in the sample. X‐ray fluorescence (XRF) captures this information from the surface of a sample. In μ‐XRF, the surface is scanned through a focused x‐ray beam, and a fluorescence spectrum is measured for each point on a 2D grid. Although this is similar to what can be done in SEM‐EDX, μXRF has some advantages over this technique such as simple sample preparation, lower detection limits and a less stringent limitation on the size of the sample. The higher penetration depth of x‐ray compared to electrons can be seen both as an advantage and a drawback. When this information is combined with μCT data, it becomes possible to fully identify the different phases seen in the 3D structure. computerised tomography; structural engineering; X‐ray fluorescence analysis
