Research student, School of Earth and Environmental Sciences
My major research interest is the formation and evolution of auriferous resources, with a particular emphasis on Archean greenstone-hosted deposits. Greenstone belts contain significant "old gold" which formed billions of years ago, in conditions which have drastically changed during the thermochemical evolution of Earth. They are relatively heterogeneous and therefore excellent subjects to study the interplay between ore genesis, Archean tetonic process and crustal differentiation.

Characterising the mineralization, alteration and temporal evolution of the auriferous Neoarchean Gokona deposit, Tanzania
Gokona is an abnormal Au deposit which is characterised by features inconsistent with orogenic and intrusion-related gold system models. These include, but are not limited to, an absence of distinct structural control, fluctuating base metal sulphide associations, mineralization which predates deformation and intense K-feldspar alteration. The available evidence suggests that the orebody formed from a shallowly circulating, high temperature magmatic fluid and warrants further investigation. The Gokona deposit is of particular interest due to relatively limited post-mineralization overprinting, presenting opportunity to examine the mineralization and alteration of an Archean intrusion related deposit in substantial detail to constrain their genesis and develop robust genetic models.
