The magmatic-hydrothermal transition in pegmatites and its effects on rare metal mineralization: insights from melt-crystal-fluid interactions in phosphate minerals from the Buranga dike (Rwanda) KU Leuven
This PhD project aims to understand the magmatic-hydrothermal differentiation process recorded at the Buranga pegmatite system (Gatumba District, Western Province, Rwanda). The Buranga dike is a type-example of a phosphorus- and boron-rich lithium-cesium-tantalum (LCT) pegmatite and well-known for its Ta-Sn-Nb mineralisation and its rich variety of primary and secondary phosphate minerals. The phosphate mineralogy records the magmatic, ...
