"Mineralogy and petrology of carbonatites, alkaline rocks and kimberlites"

The objectives of the proposed research are to understand the origin and evolution of alkaline rocks, carbonatites and kimberlites, together with their associated strategic metal economic mineral deposits. Alkaline and peralkaline syenites are host to Zr, Ti, rare earth element (REE), and P mineralization, carbonates host REE, Ti, Fe, Th, P, F and Nb deposits, and kimberlites are a source of diamond. Although alkaline rocks are of small volume relative to common silicate rocks their parental magmas are typically derived from greater depths in the Earth's upper mantle than those of such rocks, and investigation of their mineralogy and geochemistry provides insights into the metasomatic process occurring in the deeper parts of the lithospheric mantle and the asthenosphere.
