Evolution of a Conduit System at the Marathon PGE–Cu Deposit: Insights from Silicate Mineral Textures and Chemistry

Autor: David J. Good, Iain M. Samson, Doreen E. Ames, Maryam Shahabi Far, Robert L. Linnen, Joel E. Gagnon

Publikováno v: Journal of Petrology. 60:1427-1460

The Marathon platinum group element (PGE)–Cu deposit is hosted by the Two Duck Lake Gabbro of the Mesoproterozoic Coldwell Complex, Canada, and comprises three zones of mineralization, which have different textural, mineralogical and geochemical ch

Controls on the chemistry of minerals in late-stage veins and implications for exploration vectoring tools for mineral deposits: An example from the Marathon Cu-Pd deposit, Ontario, Canada

Autor: David J. Good, Doreen E. Ames, M.J. Brzozowski, Joel E. Gagnon, Iain M. Samson, R L Flemming, Robert L. Linnen

Publikováno v: Journal of Geochemical Exploration. 190:109-129

Exploration for mineral deposits is becoming increasingly difficult, requiring the use of novel approaches that are reliable and cost-effective. One such approach is the use of vein-hosted mineral chemistry. A number of studies have described the use

PGM Facies variations for Cu-PGE deposits in the Coldwell Alkaline Complex, Ontario, Canada

Autor: Doreen E. Ames, David J. Good, Louis J. Cabri

Publikováno v: Ore Geology Reviews. 90:748-771

Accurate characterization of the platinum group mineral (PGM) assemblages for Cu-Ni-PGE deposits are typically constrained by sample size and the difficulty of finding statistically significant numbers of grains, which is expected given the low conce

Insights into the extreme PGE enrichment of the W Horizon, Marathon Cu-Pd deposit, Coldwell Alkaline Complex, Canada: Platinum-group mineralogy, compositions and genetic implications

Autor: I.M. Kjarsgaard, Andrew M. McDonald, David J. Good, Doreen E. Ames

Publikováno v: Ore Geology Reviews. 90:723-747

The W Horizon, Marathon Cu-Pd deposit in the Mesoproterozoic Midcontinent rift is one of the highest grade PGE repositories in magmatic ore deposits world-wide. The textural relationships and compositions of diverse platinum-group mineral (PGM) and s

Protracted volcanism after large impacts: Evidence from the Sudbury impact basin

Autor: Paul C. Guyett, Gavin G. Kenny, Doreen E. Ames, Teresa Ubide, Nancy R. Riggs, Edel M. O’Sullivan, Balz S. Kamber, Joseph A. Petrus

Publikováno v: Journal of Geophysical Research: Planets. 122:701-728

Morphological studies of large impact structures on Mercury, Venus, Mars, and the Moon suggest that volcanism within impact craters may not be confined to the shock melting of target rocks. This possibility prompted reinvestigation of the 1.85Ga suba

Chemostratigraphy of the Sudbury impact basin fill: Volatile metal loss and post-impact evolution of a submarine impact basin

Autor: Robbie Goodhue, Edel M. O’Sullivan, Doreen E. Ames, Balz S. Kamber

Publikováno v: Geochimica et Cosmochimica Acta. 183:198-233

The 1.85 Ga Sudbury structure provides a unique opportunity to study the sequence of events that occurred within a hydrothermally active subaqueous impact crater during the late stages of an impact and in its aftermath. Here we provide the first comp
