Combining Micro-XRF and Micro-CT for Drill Core Analysis

This technical report details the analysis of a sectioned drill core using two advanced techniques: micro X-ray fluorescence spectrometry (micro-XRF) and micro computed tomography (micro-CT). The objective is to demonstrate how these methods can be combined to generate comprehensive mineral information from the drill core sample. Micro-XRF provides detailed 2D element distribution maps, while micro-CT offers 3D reconstructions of material densities. The report outlines the measurement conditions for both techniques, including the equipment used and the specific parameters set during the analysis. Results from the micro-XRF reveal the presence of various minerals, including iron oxides and silicates, while the micro-CT data illustrate the relative distribution of these minerals based on their attenuation coefficients. The findings indicate that the integration of both methods enhances the understanding of mineral composition and distribution within the sample, providing a more complete picture than either method could achieve alone.
