Survey Projects


  • Compilation of maps and report of mapping of Mesoproterozoic anorthositic and associated rocks in the Nain area, 1:50 000 scale; mapping augmented with contract geochronology (1999-2007).


  • 1:50 000 and 1:100 000 scale mapping of Archean and Paleoproterozoic rocks of the Saglek - Hebron area, northern Labrador (1982-83).
  • 1:50 000 and 1:100 000 scale mapping of Archean and Paleoproterozoic gneisses and Mesoproterozoic rapakivi granite in the Labrador coast to Quebec border area west of Nain (1985-88).
  • 1:50 000 scale mapping of Archean gneisses on the archipelago east of Nain and reconnaissance examination of Paleoproterozoic and Mesoproterozoic intrusive rocks north and west of Nain (1990-94).
  • 1:50 000 and 1:100 000 scale mapping of Archean gneisses, Paleoproterozoic anorthositic and granitic intrusions, and Mesoproterozoic anorthositic and granitic intrusions of the Okak Bay area (1996-97).
  • 1:50 000 mapping of anorthositic rocks between Nain and the Kingurutik River (1999-2004).

Research Interests

  • Crustal evolution.
  • Orogenic processes.
  • Petrogenesis and emplacement of anorthositic plutons and the development of anorthositic batholiths.
