Dr Nigel Cook

Qualifications

I graduated with a BSc in Geochemistry from Queen Mary College, University of London, U.K., in 1982 and a PhD in mineral deposit geology from Imperial College, University of London, U.K., in 1988. Later (1998), I obtained the Habilitation degree from the University of Würzburg, Germany.

Research Interests

My work over the past 20 years has been directed to the geology and mineralogy of sulphide ore deposits. In particular, I have aimed to analyse and interpret mineral assemblages, mineral chemistry and textural evidence to understand the genetic history of mineral deposits, and to discover controls on element partitioning, paragenesis and mineral stabilities. The approach has encompassed major, refractory mineral phases (e.g. pyrite), as well as the trace components such as sulphosalts and tellurides. Studies have been applied to deposits ranging from volcanic-hosted and SEDEX-type massive sulphides, epithermal precious metal, porphyry and skarns, and even liquid-magmatic Cu-Ni-PGE deposits. My research has often been of a generic character, i.e., common problems are applied to deposits across the world and across geological time, rather than to specific deposits or ore provinces.

Personal milestones include:

·    Identification of pyrite as a major host for lattice-bound or sub-microscopic (‘invisible) gold’; work on the role of Bi-chalcogenides as precious metal carriers and on the distribution of trace elements (In, Ge, Ga etc.) in sphalerite.

·    Demonstrating the role that pyrite textures can play in deciphering the metamorphic history of deformed metamorphosed VMS deposits (Scandinavian Caledonides, Namibia, Romania); identifying the role and mechanisms involved in recrystallization of the major sulphides and the subsequent remobilization of trace elements

·    Assessment of the role of Cu-Ag-Pb-Bi sulphosalts, tellurides and selenides and the potential of Bi-chalcogenides as petrogenetic indicators in gold deposits ranging from Archean orogenic-gold deposits to telluride-rich volcanic-epithermal systems of Tertiary age.

·    Research on key mineral groups, including the (Fe,Ni,Co,Cu)₃S₄ thiospinel group, cuprobismutite and related Cu-Bi sulphosalts, and phases in the Bi-Te-Se-S system.

 

Correlation of trace mineralogy and mineral chemistry of the major sulphides has been a central theme. I aim to show how mineralogical study can and should be applied to solve a range of questions in ore geology, and how research on the micro- or nanoscopic scales can be placed in the context of the orefield-scale geologic setting and regional metallogeny.

Nigel arrived in the School of Earth and Environmental Sciences, University of Adelaide in August 2009 from the Natural History Museum at the University of Oslo (Norway). He holds a joint position with the South Australian Museum.

Nigel serves as President of the International Association on the Genesis of Ore Deposits (IAGOD) from 2008 to 2012, having previously been Secretary General of the association (2000-2008). He is also Editor-in-Chief of the journal Ore Geology Reviews.

Nigel served as Chairman of the International Mineralogical Association Commission on Ore Mineralogy between 2006 and 2010.

He holds an adjunct Professorship at the Department of Geology, University of Turku, Finland.

From 2003 to 2008, he co-ordinated International Geoscience Programme Project 486 ‘Gold telluride deposits’.

His research over the past 20 years has focussed on the genesis of base- and precious metal ore deposits, with emphasis on understanding ores through their ore mineralogy and textures, processes of remobilisation, and the distribution of trace elements and minerals.

In the past five years he has been involved in research in Norway, Svalbard, Finland, China, Canada, Romania, Uzbekistan and Australia.
