(Zeiss Mineralogy software)
Mineralogy of polished sections can be automatically categorised by the Zeiss Mineralogic software. Before analysis and classification of minerals, the mineral library for the analysis needs to be updated by a geologist to match the exact mineral composition for the samples in the project. During analysis, the software creates a false-coloured image based on the underlying Back-scattered electron image and the interpretation of chemical analyses (EDS) for each pixel of the image. The software includes options for mining, like liberation and interlocking analyses, and reservoir analyses, like porosity measurements.
Example of an element map showing two types of pyroxene (green and wine-red), ilmenite (orange) and olivine (pink) in plagioclase (blue). Width of view: ca. 8 mm. Pixel size 10 µm.
The same software can also be used for particle analysis (Computer-controlled scanning electron microscopy, CCSEM). Here, the major and minor element chemistry, grain morphology, liberation, association and locking parameters can be determined on an individual grain basis. The technique can be applied to loose grains or heavy minerals in epoxy mounts and is often applied for provenance, mining and exploration studies.
Automated particle analysis applying the CCSEM technique with the Zeiss Mineralogic software. The mineral classification is per particle, allowing for a faster analysis of the sample.
