A geological and geophysical synthesis of the Chapais region: eastern part of the Quebec Abitibi Belt

The Chapais region has been extensively studied during the last 40 years. Recent work in this area has provided information that can be used to assess the various models proposed for similar volcano-sedimentary belts. By using the known surface geology and measured rock densities, gravity interpretation can define the structure of the geological formations. Aeromagnetic data have been used to improve surface mapping in areas of few or no …
