Abstract

The aim of this field trip is to illustrate the geological setting and controls on gold mineralization in the Cadillac-Bousquet mining district, the major gold producing district in the Quebec Abitibi belt (Fig.1). The development of auriferous system in this area are invariably associated with major tectonic features in the volcano-sedimentary pile. The regional tour will focus on the dominant structural and stratigraphic features of the various lithological units and on the structural controls of gold mineralization. The underground tour and surface visits will allow participants to become acquainted with the complex geology of an area, that hosts several types of gold mineralization. To date, approximately 79,800 kg of gold have been extracted from over 11 orebodies on the Doyon, Bousquet and Dumagami properties (Marquis, 1990). Proven and probable gold reserves for the district are estimated to be more than 230 tonnes of gold at an average grade of 5,1 grams per tonne (Marquis, 1990).
