Curriculum Vitae

Research Interests

My primary interests lie in applying metallogenic theory to mineral exploration. The main focus of my work has been in conducting regional metallogenic analysis, i.e. placing ore forming processes within regional structural/stratigraphic frameworks based on field relationships. Areas of field study include the Archean Superior and Slave cratons, the Proterozoic Southern, Churchill, Bear and Grenville provinces, and the Phanerozoic Appalachian and Cordilleran orogens. I have been mostly engaged with exhalative basemetal ores in rift settings and precious metal concentration within domains of post orogenic collapse.

Courses Taught

Undergraduate Courses

Earth Sciences 3370a/3371b: Mineral Deposits Geology (1983-present)
Full third-year course, split into two half-year courses in 1993. Lectures cover all important metallic ore deposits presented within the framework of one complete metallogenic cycle. Labs focus on reflected light microscopy of representative ore suites.

Earth Sciences 4470a: Mineral Deposits and Crustal Evolution (1993-present)
Fourth-year half course. Lectures present geological evidence for supercontinental cyclicity since the end of the Archean and accounts for the non-uniformitarian evolution of mineral deposits.

Earth Sciences 4450y: Fourth Year Field Camp (1986-88, 1993-97)
Two-week trip through the Appalachians, the Grenville, and the Abitibi. Counts as half-course credit. (With W. Church until 1996.)

Earth Sciences 3350y: Third Year Field Camp (1998-2006)
Two weeks GPS/GIS field mapping in the Sudbury area. Counts as half-course credit. (With W. Church.)

Earth Sciences 2250y: Second Year Field Camp (1994)
Second-year field camp. Two weeks at a base camp at Whitefish Falls, with regional trips in the Sudbury area. Counts as half-course credit. (With Grant Young.)

Earth Sciences 4490e: Fourth Year Thesis Supervision
45 completed

Graduate Courses

Geology 9550 Global Metallogenic Cycles in Crustal Evolution (1998-present)
See under fourth year above.

Geology 9551a/b Case Histories in Regional Metallogenic Analysis (1984-present)
Half course. Takes modern concepts of terrane analysis as a point of departure. Lectures present a series of case studies drawn from past and ongoing field projects.

Geology 9552 Advanced Studies in Mineral Deposits (1998-02)
Half course taught on an occasional basis on demand. Special topics depending on student interest.

Exploration for Hydrothermal Ore Deposits (2001, 2003, 2005)
Modular half-course equivalent offered by Laurentian University. (2001 organized with H. Gibson).
