I am interested in deformation processes in the Earth at all scales, especially in the upper crust, and their relation to the formation of hydrothermal mineral deposits.

Fracturing, fluid flow, and brecciation are critical in these environments. I am also interested in the relationship between tectonics and surface processes in rifts and continental interiors. In many of these topics, techniques based on fractal geometry are important tools.

Economic Impacts in Mineral Exploration and Mining

My ressearch in hydrothermal mineralization is highly relevant to the exploration and mining industry. Exploration can be directed more efficiently, and resources estimated more accurately, by understanding structural controls on mineralization. More efficient explration programs also benefit the environment.

The research has been carried out in Australia, Brazil, Papua New Guinea, Russia, West Africa, and southern Africa, mainly through consultancies to mining companies including Anglogold Ashanti, Glencore, Highlands Paciifc, Kinross, Newmont Asia Pacific, Rio Tinto, Ozminerals, and Zimplats. Most of this work is concerned with hydrothermal gold and copper deposits, including lode gold, epithermal, VHMS deposit types. Anglogold Ashanti, Kinross and Newmont are three of the top ten gold mining companies in the world.

Exploration relies heavily in diamond drill core. I have been developing unified systems for analysing orientated drill core, paying special attention to linear features such as fold hinges and slickenlines which are vital but commonly ignored. These methods are outlined in a couple of papers and implemented in a spreadsheet for calculating structural orientations of planar and linear features from core measurements.

Profession Practice Impacts - Training

Teaching courses on structural geology for exploration and mining has been a signficant part of these industry relationships. Structural geology is a rapdly advancing discipline, and many of the latest ideas have important ramifications for exploration, which are built into these courses. Practical and field components are essential parts of the courses.

In March 2020, a new MOOC from Cardiff University "Structural Geology for Exploration and Mining" will take some of these ideas to a wider audience.

The final stages of a textbook are in preparation, which will be a new look at structural geology at an intermediate to advanced undergraduate/postgraduate level, with coathors Steve Wojtal adnd Basil Tikoff.
