Economic Geology

The University of Otago Geology Department has an active staff and student economic geology research program. We apply a range of techniques from field mapping to high resolution imaging by scanning electron microscopy to stable and radiogenic isotope geochemistry to interpret how and why deposits have formed. Environmental aspects are covered too, especially around the processing sites of historic mines. We collaborate closely with mining companies, such as Oceana Gold, and crown research institutes, such as GNS Science.

Economic Geology research

We have extensive webpages detailing some of our economic Geology research:

This research has culminated in the publication of these two books:
