Development of a simple qualitative methodology for a quick characterization of silica nodules (case of study for the time being but not limited to), combining the results of reconstruction and 3D visualization provided by x-ray computed tomography (XCT), 2D elemental distribution via micro x-ray fluorescence (μ- XRF), and mineral composition with micro x-ray diffraction (μ-XRD).
The concept is to use XCT as the starting point for further characterization of spherical nodules found in El Tatio, a hot spring located in northern Chile. The 3D visualization provides a powerful tool to decide where to make a cuts to get slices of interest for further μ-XRF analysis of major elements distribution and mineral-ogy with μ-XRD.
