Interests

Faults in the Earth's crust affect us daily in many ways. Apart from their role as the focus of earthquakes, in the past movement of fluids along faults has mineral deposts. I am interested in all aspects of how the crust deforms, mineral deposits, and plate tectonics.

  • Structural Geology
  • Hydrothermal mineral deposits
  • Faults, fluid flow, brecciation and granular flow
  • Surfaces processes and tectonics
  • Archean tectonics

I teach structural geology at second, third and fourth year levels. Fieldwork and field based teaching are the best way to teach this subject, as demonstrated by feedback from generations of students. My classes go to the south Wales coast, to Arran and to North Spain.

The potential of drones to provide outstanding perspectives in the field is obvious, as well as generating lots of interest from a teaching point of view.

Measuring structures in drill core is a vital skill in the exploration industry: I am developing some teaching materials for this skill.

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 several of these topics, techniques based on fractal geometry are important tools that I apply.

Granular flow is widespread in industrial processes such as pouring concrete, aswell as on and in the Earth, for example in avalanches, debris flows and along faults. Quite a sophisticated understanding of granular flow exists in the Physics and Engineering communities. We have only just started to apply these ideas to Earth science. One application is the possibility that magmatic ore deposits form by granular flows of crystals within intrusions.

Together with my colleague Prof. Owen Jones in Maths here at Cardiff, I am researching aspects of georesource utilisation and sustainability. What can the concept of peak inerals tell us about resource availability? Will we be able to find enough copper or the transition to a hydrocarbon free society in which electricity production and transport will become so important?

Structural Geology for 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 if structural controls on mineralization are understood.

This has lead to work in Australia, Papua New Guinea, Brazil, West Africa, and southern Africa, mainly through consultancies to mining companies including Newmont Asia Pacific, Angold Ashanti, Highlands Paciifc, Rio Tinto, Ozminerals, Glencor, and Zimplats.

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.

In 2019, a new MOOC from Cardiff University 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.
