- 01J8FCBYFPNTWR2SC3P0TKGA19 abstract "The Mesoproterozoic Karagwe-Ankole belt (KAB) in Central Africa hosts important mineralized Lithium Caesium-Tantalum (LCT) pegmatites enriched in Sn, Nb, Ta and W. It is expected that research on pegmatites will remain crucial as many of the searched-for critical elements in clean energy technologies are associated with LCT pegmatites. Notwithstanding many decades of geological research on mineralized pegmatites, the exact processes and formation conditions that lead to the concentration of these critical elements are yet not fully understood. Therefore, the detailed documentation of the textural variability of the pegmatite-forming minerals in naturally occurring deposits is necessary for the verification of the crystallization response in experimental simulations and to contribute to fundamentally new concepts about how the concentration of critical elements is controlled by the fluxing components. Using a combination of scanning electron microscopy (SEM)-based automated mineralogy systems with X-ray computed tomography (µCT), we investigated the mineral relationships in a three-dimensional (3D) space. The textural complex and mineralogical diverse assemblages could now be fully studied in 3D which offered new insights regarding their crystallography and spatial association. The 3D automated mineralogy assisted in the identification of minerals (e.g., identification of Fe-Li mica and the inclusion of a barite veinlet in a muscovite grain) and the localization of key mineral assemblages that further helped to refine the paragenesis of mineralized pegmatites in the KAB. A stage of albitization followed the primary crystallization and muscovite was found to probably play a role in the fluid migration and the subsequent precipitation of ore minerals. An important observation from µCT data is a mineral assemblage of quartz-albite-tourmaline-muscovite that revealed a stage of from greisen pockets confirmed the suggested hydrothermal formation conditions. A first-time description of oriented zircon and the association with flat tabular columbite-tantalite pointed to the importance of local magmatic-hydrothermal conditions. This presentation emphasizes the possibilities of using 3D automated mineralogy for the identification of minerals and their position in the paragenetic history of mineralized pegmatites and by extension of other complex ore deposits.".
