| 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. |
| Summary | (Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI) is directed towards providing next generation knowledge and methods to facilitate more effective targeting of
buried mineral deposits. The program aims to enhance the effectiveness of exploration for Canada¿s major mineral systems by resolving foundational geoscience problems that constrain the geological processes responsible for the liberation metals from
their source region, transportation of these ore metals and control their eventual deposition. TGI supports projects on gold, Ni-Cr-PGE, porphyry-style mineralization, uranium and volcanic- and sedimentary-hosted base metal mineralization ore
systems, with each project divided into subprojects focused on resolving specific knowledge gaps by integrating data and studies from multiple sites across Canada. Herein, we present interim results and interpretations from a selection of the
research activities currently being conducted under the auspices of TGI. |
