Dr. J.B Whalen
Current research and/or projects
Granitic rocks underlie a large proportion of Canada and host economically important mineral resources. Joe Whalen's research combines geological, geochemical, isotopic and geochronological studies of granites to: (1) map different age crustal domains/blocks on a regional scale; (2) understand tectonic processes responsible for magmatism during orogenic belt formation/evolution; (3) substantiate cogenetic relationships between plutonic suites and mineralization; and (4) identify granite protoliths and the relative roles of crustal recycling, new mantle additions and crust-mantle interaction in their formation and implications for evolution of continental crust during Earth history. This research has contributed to high quality geological maps of economically important areas (e.g. Bathurst, Buchans, Flin Flon-Snow Lake, Thompson, Red Lake, Sturgeon Lake, Endako mining camps). Over the last 25 years he has been involved in projects within the Appalachians (QC, NF, NB, NS), Cordilleran (BC), Superior (ON, MB), and Trans-Hudson (MB, SK) orogens/provinces. Collaborators include GSC, provincial government and university scientists.
Recent studies include: post-collisional volcanic arc to within-plate magmatism related to slab breakoff (Red Indian Line TGI project, NF) granitoid geochemical-Nd isotopic transects between (1) Ungava, QC and central Baffin and (2) Thompson and Snow Lake MB (Trans Hudson-Superior Margin Metallotech project) tonalite-trondhjemite-granodiorite (TTG) petrogenesis and using granites as crustal probes to map different large-scale crustal blocks (Western Superior NATMAP project, ON-MB),Francois Lake plutonic suite progenitor to the Endako Mo mine (Nechako NATMAP project, BC).
Education and awards
Dr. Whalen obtained an Hon. B.Sc. in 1974 from the University of Western Ontario,an M.Sc. in 1976 from Memorial University of Newfoundland, and a Ph.D. in 1981,from Australian National University. He joined the Geological Survey of Canada in 1981.
