Edited by Kent Condie, Elsevier's Developments in Precambrian Geology book series is designed to provide a comprehensive source of detailed information on all aspects of the Precambrian, including (1) chemical, biological, biochemical and cosmochemical evolution; (2) geochemistry and geochronology; (3) geophysical aspects of the early Earth; and (4) nature and evolution of the lithosphere. The Precambrian rocks, older than 2, m.y., in the Saganaga Lake-Northern Light Lake area on the Minnesota-Ontario boundary include a thick succession of metavolcanic rocks, chiefly greenstone but with some intermediate to silicic types, and minor metasediments; the Northern Light Gneiss; the Saganaga Tonalite; alkalic syenodiorite and granodiorite; and the Knife Lake Group.

The Canadian Shield or Bouclier canadien (French), also called the Laurentian Plateau, is a large area of exposed Precambrian igneous and high-grade metamorphic rocks (geological shield) that forms the ancient geological core of the North American continent (the North American Craton or Laurentia).
