Publikováno v: Communications Earth & Environment, Vol 5, Iss 1, Pp 1-12 (2024)
Abstract Magmatic volatile phases play a major role in igneous systems, but indirect sampling of the magmatic fluid, especially for basic magmas, remains challenging to document. Here, we report compelling evidence of primary fluid inclusions trapped

Autor: Xuyang Meng, Jackie M. Kleinsasser, Jeremy P. Richards, Simon R. Tapster, Pedro J. Jugo, Adam C. Simon, Daniel J. Kontak, Laurence Robb, Grant M. Bybee, Jeffrey H. Marsh, Richard A. Stern
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-9 (2021)
Tectonomagmatic conditions in the Precambrian were hypothesized to be unfavorable for porphyry Cu deposit formation. Here, the authors show that metallogenic processes typify Phanerozoic porphyry Cu deposits operated by ~1.88 Ga, reflecting modificat

Discriminating Between Primary and Secondary Au Events in a Paragenetically Complex Archean Lode-Gold Deposit, Wawa Gold Corridor, Ontario, Canada
Autor: Elliot A. Wehrle, Jean-François Montreuil, Iain M. Samson, Daniel J. Kontak, Mingqian Wu
Publikováno v: Economic Geology. 118:347-370
The Wawa gold corridor, located in the Michipicoten greenstone belt of the Superior province, Canada, comprises Au-bearing shear zones that crosscut the 2745 Ma Jubilee stock and that evolved during protracted deformation (D1-D3). Numerous generation

Evaluating Geochemical Discriminants in Archean Gold Deposits: A Superior Province Perspective with an Emphasis on the Abitibi Greenstone Belt
Autor: E.C.G. Hastie, D. J. Kontak, B. Lafrance, J. A. Petrus, R. Sharpe, M. Fayek
Publikováno v: Economic Geology. 118:123-155
Discriminating Archean Au deposit types and related ore-forming processes is challenging but paramount for increasing Au exploration success. This study tests the validity of applying geochemical data generated from conventional bulk versus modern in

The age and origin of the South Mountain Batholith (Nova Scotia, Canada) as constrained by zircon U–Pb geochronology, geochemistry, and O–Hf isotopes
Autor: Luke Bickerton, Daniel J. Kontak, J. Brendan Murphy, Dawn A. Kellett, Iain M. Samson, Jeffrey H. Marsh, Greg Dunning, Richard Stern
Publikováno v: Canadian Journal of Earth Sciences. 59:418-454
The South Mountain Batholith (SMB; Nova Scotia, Canada) is the largest composite batholith exposed in the Appalachians and lies entirely within the most outboard Meguma terrane. In situ and CA–TIMS U–Pb dating and in situ isotopes (Lu–Hf, O) an
