Platinum-group elements (PGE) are some of the rarest and most valuable metals on Earth, used in a quarter of all manufactured goods worldwide according to the International Platinum Group Metals Association. My PhD project investigates the PGE signatures of mantle plumes around the world, using a combination of geochemistry and isotope analyses to uncover the role mantle processes play in magma metal budgets. Plumes, upwellings of hot material from inside the Earth not strictly related to plate tectonics, can interact with two main PGE reservoirs - the core and the sub-continental lithospheric mantle (SCLM). If plumes can incorporate even small amounts of these reservoirs into melts they induce at the lithosphere, the PGE contents of their resultant magmatic deposits are expected to be significantly enriched. 

Throughout my project, I will be comparing the geochemistry of plume-derived lavas from Paraná, Etendeka, Hawaii, Iceland, the Canary Islands and Ontong-Java to determine if plumes have similar PGE signatures and what causes any variability if they differ. I aim to test two major hypothesis in my research - 

     1) Deep mantle plumes (originating near the core) will be more enriched in PGE than shallow mantle plumes.

     2) Plumes close to or within the continental crust/SCLM will have different PGE ratios than plumes within the oceanic crust.

Information obtained from geochemical and Os, He and W isotopic data will allow me to contrast and compare the plumes I study (and others using published datasets) to qualitatively assess what makes a "good" plume for mineralisation potential.
