Synthse gologique et gophysique de la rgion de Chapais : portion orientale de la ceinture de l'Abitibi qubcoise

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 …
