ABSTRACT This paper presents the results of a detailed study of the Kiena mine where precise U-Pb zircon dating of an intermineral granodiorite dike assigns a minimum age of 2686 Ma to an Archean intrusion-related gold vein system. The age reveals that gold mineralization post-dates volcanism (ca. 2718-2700 Ma) but predates regional synmetamorphic deformation (ca. 2677-2645 Ma) and the intrusion of S-type granitoids across the Abitibi and Pontiac subprovinces (ca. 2645-2611 Ma). -from Authors
