Three-Dimensional Mapping of Soil Chemical Characteristics at Micrometric Scale by Combining 2D SEM-EDX Data and 3D X-Ray CT Images
Fig 4
Illustration of SEM-EDX chemical mapping and the corresponding layer within the 3D X-ray CT data.
The intensity of the colour indicates the concentration of the elements, whereas the grayscale intensity of the X-ray CT image reflects the density of the material.
