The Francoeur 3 gold deposit, located approximately 15 km southwest of Rouyn-Noranda, Quebec, is one of several geologically similar Archean mesothermal gold deposits occurring along the Francoeur-Wasa shear zone, a second-order reverse structure possibly related to the Cadillac-Larder Lake break.The principal gold mineralization, which is completely ...

Abstract New Re–Os ages for early concordant veins and later discordant veins in the Ikalamovony sub-domain of west-central Madagascar require respectively a Paleoproterozoic age for metasedimentary rocks and a Pan-African age for the orogenic type occurrences. Indeed, this paper focuses on Re–Os geochronology of Dabolava gold occurrences, located in

Abstract Study of the Miocene Porgera intrusive rocks over 40 yr has generated at least four mutually contradictory classification schemes. These rocks are here reassessed, using a computer database of 256 analyses of volcanic and intrusive rocks of similar age from Papua New Guinea (PNG), and 100 analyses of the Porgera rocks themselves. The Porgera

Archean gold-bearing quartz vein systems constitute one of the most important classes of precious metal deposits; however, their origin remains controversial. Mantle, granitoid, meteoric water, and metamorphic related models do not resolve this controversy.
