Research Areas

Research Overview

Early Precambrian crustal evolution and tectonics, climate, environment and emerging life. This is undertaken via integrated field studies (including detailed geological mapping), geochemistry, petrography and zircon U-Pb geochronology.

Zirconology in general, not only U-Pb dating but using zircon trace element geochemistry and inclusion suites of other minerals as tracers of crustal evolution, surficial processes and the evolution and origin of orebodies

Palaeozoic crustal evolution in eastern Australia, with emphasis on the New England Orogen and the Macquarie arc.

Education And Training

Ph.D. in Geology, Exeter University, Department of Geology 1976 - 1980

Teaching Overview

I taught a range of undergraduate and graduate subjects at Memorial University of Newfoundland 1984-1988.

In University of Wollongong subjects taught are:

2010-2016 EESC101 'Planet Earth' an introduction to the solid Earth - its structure, evolution, rocks, minerals etc.

2010-continuing EESC201 'Earth's Inferno' the second year igneous and metamorphic petrology subject.

I have introduced many innovations into these subjects, including digital online resources such as 'Petroscope', the deployment of more 'real-life' assessment items and deployment of Hi-Tech equipment in teaching, such as the hand-held-XRF.

My goal is to embed the range of laboratory, field and computational skills necessary for a professional Geoscientist.

Research Areas

Research Overview

Early Precambrian crustal evolution and tectonics, climate, environment and emerging life. This is undertaken via integrated field studies (including detailed geological mapping), geochemistry, petrography and zircon U-Pb geochronology.

Zirconology in general, not only U-Pb dating but using zircon trace element geochemistry and inclusion suites of other minerals as tracers of crustal evolution, surficial processes and the evolution and origin of orebodies

Palaeozoic crustal evolution in eastern Australia, with emphasis on the New England Orogen and the Macquarie arc.

Education And Training

Ph.D. in Geology, Exeter University, Department of Geology 1976 - 1980

Teaching Overview

I taught a range of undergraduate and graduate subjects at Memorial University of Newfoundland 1984-1988.

In University of Wollongong subjects taught are:

2010-2016 EESC101 'Planet Earth' an introduction to the solid Earth - its structure, evolution, rocks, minerals etc.

2010-continuing EESC201 'Earth's Inferno' the second year igneous and metamorphic petrology subject.

I have introduced many innovations into these subjects, including digital online resources such as 'Petroscope', the deployment of more 'real-life' assessment items and deployment of Hi-Tech equipment in teaching, such as the hand-held-XRF.

My goal is to embed the range of laboratory, field and computational skills necessary for a professional Geoscientist.
