| Abstract | The Abitibi greenstone belt and the emerging Paleozoic gold district across the central Newfoundland Appalachians both extend over similarly sized areas and are characterized by crustal-scale faults
associated with remnants of synorogenic clastic basins. The aim of this study to investigate whether the orogenic model for structurally controlled Archean lode gold deposits developed for the Abitibi belt is applicable to Newfoundland and, by
extension, other regions. Although the Abitibi belt has a substantially greater gold endowment than the Newfoundland belt, this research is focused on a compare and contrast exercise with respect to lithology, stratigraphy, structure, magmatism and
tectonic setting. Identifying similarities between Archean and Paleozoic gold districts may identify recurring orogenic processes and key ingredients that are fundamental to the development of structurally controlled gold systems. |
