Age and Chemostratigraphy of the Finlayson Lake District, Yukon: Implications for Volcanogenic Massive Sulfide (VMS) Mineralization and Tectonics along the Western Laurentian Continental Margin

Autor: Matthew J. Manor, Stephen J. Piercey, Donald C. Murphy, Corey J. Wall

Publikováno v: Lithosphere, Vol 2022, Iss 1 (2022)

AbstractThe Yukon-Tanana terrane in the Finlayson Lake district, Yukon, represents one of the first arc–back-arc systems that formed adjacent to the Laurentian continental margin in the mid-Paleozoic. Back-arc rocks contain many large and high-grad

Birth of the northern Cordilleran orogen, as recorded by detrital zircons in Jurassic synorogenic strata and regional exhumation in Yukon

Autor: Maurice Colpron, Donald C. Murphy, George E. Gehrels, James L. Crowley, Luke P. Beranek, Darrel G.F. Long, Luke Bickerton

Publikováno v: Lithosphere. 7:541-562

The Whitehorse trough is an Early to Middle Jurassic marine sedimentary basin that overlaps the Intermontane terranes in the northern Cordillera. Detrital zircon dates from eight Laberge Group sandstones from various parts of the trough all display a

Lithosphere-asthenosphere mixing in a transform-dominated late Paleozoic backarc basin: Implications for northern Cordilleran crustal growth and assembly

Autor: Stephen J. Piercey, Robert A. Creaser, Donald C. Murphy

Publikováno v: Geosphere. 8:716-739

The Slide Mountain terrane is part of a North American Cordillera–long backarc basinal assemblage that developed between the ensialic arc terranes (Yukon-Tanana and affiliated pericratonic terranes) and the North American craton in the middle to la

Petrology and U-Pb Geochronology of Footwall Porphyritic Rhyolites from the Wolverine Volcanogenic Massive Sulfide Deposit, Yukon, Canada: Implications for the Genesis of Massive Sulfide Deposits in Continental Margin Environments

Autor: Terry L. Tucker, Stephen J. Piercey, Jan M. Peter, Donald C. Murphy, James K. Mortensen, Suzanne Paradis

Publikováno v: Economic Geology. 103:5-33

Porphyritic rhyolite sills form an important component of the footwall of the Wolverine volcanogenic massive sulfide (VMS) deposit, Yukon, Canada, and occur proximal to mineralization in the immediate deposit area (Wolverine/Lynx zone) and at similar

Yukon–Tanana terrane in the southern Campbell Range, Finlayson Lake belt, southeastern Yukon: the geological setting of retrogressed eclogite of the Klatsa metamorphic complex

Autor: Sharon D. Carr, Fionnuala Devine, Donald C. Murphy

Publikováno v: Canadian Journal of Earth Sciences. 44:317-336

Yukon–Tanana terrane in the southern Campbell Range is composed of rocks that have different metamorphic, exhumation, and structural histories, and that have formed in disparate parts of the Paleozoic Yukon–Tanana volcanic arc. The geological rel

Geochemistry and tectonic significance of alkalic mafic magmatism in the Yukon-Tanana terrane, Finlayson Lake region, Yukon

Autor: Donald C. Murphy, Suzanne Paradis, Robert A. Creaser, Stephen J. Piercey, James K. Mortensen

Publikováno v: Canadian Journal of Earth Sciences. 39:1729-1744

This paper provides an integrated field and geochemical study of weakly alkalic, ~360 Ma mafic rocks from the YukonTanana terrane in the Finlayson Lake region, southeastern Yukon. These mafic rocks occur as dykes and sills that crosscut older felsi

Geochemistry and Paleotectonic Setting of Felsic VolcanicRocks in the Finlayson Lake Volcanic-Hosted Massive Sulfide District, Yukon,Canada

Autor: Stephen J. Piercey, Donald C. Murphy, James K. Mortensen, Suzanne Paradis

Publikováno v: Economic Geology. 96:1877-1905

The Finlayson Lake volcanic-hosted massive sulfide (VHMS) district represents one of Canada’s most recent VHMS discovery regions with ~34 million metric tons (Mt) of massive sulfide mineralization found since the mid 1990s. Felsic volcanic rocks ar
