My general research interests are in the field of structural geology and tectonics, with an emphasis on upper crustal deformation mechanisms and microstructures (I have published a book on this topic ). I am interested in applications of structural geology in ore deposit studies, and applications of fractal geometry in the Earth Sciences, and particularly in economic geology.
Some current research projects are:
Breccias and Brecciation mechanisms. Development of new and automated methods of breccia characterisation and their use to determine mechanisms of brecciation.
Kinematic and Dynamic Methods of Fault Slip Analysis.
Hydrothermal mineralization – especially gold and copper, throughout the geological record
Tectonics and landscape development, focussing on Southern Africa
Archean tectonics and intrusion mechanisms of Archean granites
Brief description of research impact:
The Total Systems Analysis of the Mt Isa Eastern Succession module of the pmdCRC (for which I was project leader) is stimulating and guiding exploration for base metals in the eastern part of Mt Isa. It has suggested a new model for the genesis of iron oxide copper gold ore deposits.
Research in hydrothermal gold mineralization, partly carried out in conjunction with PhD students, is being used in mine and regional scale exploration.
