Speaker Spotlight: Rick Sibson

14 February 2019

Richard (Rick) Sibson’s research focuses on the structure of crustal fault zones and the mechanics of shallow crustal earthquakes with subsidiary interests in crustal fluid flow and structural controls affecting the development of fault-hosted mineralisation. He is author or co-author of over 100 research papers and has delivered short courses to the mineral industry and academia across the globe. You can read his full bio here.

Rick will present his paper Subduction seismic style, fluid release, and orogenic gold mineralisation in forearc settings on Friday 5 April, 2019.

We recently asked Rick some questions about PACRIM. See his answers below:

1. Can you provide an insight into what your presentation will cover at PACRIM 2019?

(i) Varying seismic style accommodating displacement along subduction interfaces;
(ii) State of fluid overpressuring along subduction interfaces;
(iii) High fluid content of overpressured reservoirs along the subduction interface

2. What do you hope delegates will learn/take away from your presentation?

The likelihood that subduction interfaces are a source of overpressured Au-mineralizing hydrothermal fluids.

3. What are you looking forward to most about PACRIM?

Interacting with the MINEX community.

4. What is the biggest challenge you have faced in your career?

Identifying my own areas of ignorance and doing something about them.

5. What advice would you give to a young professional beginning their career in the resources sector?

(i) Gain the greatest possible appreciation of active geological processes from geology, tectonics, geophysics and geochemistry. Learn to think ‘fast and intermittent’ where appropriate, rather than ‘slow and steady’.

(ii) Gain an appreciation of the controls on structural permeability in the crust and how they work.

(iii) Understand that ‘The Past is the Key to the Present’ as well as ‘The Present is the Key to the Past’ – it cuts both ways!
