Mineralogy and geochemistry of selected granitic pegmatites in Uganda

Pegmatites are important sources of several rare elements which are essential for development of modern technologies. The pegmatite deposits in Uganda had been explored and mined until the early 1970’s. At present, they are being re-evaluated and exploration for new deposits is ongoing. Auranda is seeking to establish models for mineral production based on certified, conflict-free production and trading chains. The main objective of this project is to improve the knowledge of the rare-element pegmatite occurrences in central and southern Uganda, while training the next generation of geologists in pegmatite exploration techniques, which can be applied to potential deposits being identified in Canada. Field work, electron microprobe, cathodoluminescence microscopy, geochronology, and other techniques will be used to:
1. Determine the spatial distribution of rare-element pegmatites and the regional zoning of individual pegmatite groups.
2. Identify the affiliation of pegmatites to their parental granites.
3. Assess the accuracy and practicality of mica geochemistry and mineralogy as an exploration tool for non-exposed rare-element pegmatites.
4. Distinguish metamorphic, pegmatitic and hydrothermal quartz.
5. Assess fractionation degree, classification, depth of origin, and types of post-magmatic processes affecting the rare-element mineralization.
