... in the Hornby Bay and Thelon basins, unmineralized sandstone in the Athabasca Basin contains “crandallite group” and fluorapatite cements higher in the basin fill sequence (Wolverine Point Formation) in tuffaceous sandstone and as relatively early cement in the paragenetic sequence. Corresponding author (e...

... near the northern margin of the Athabasca Basin scatter about isochrons of 2.6 Ga, reflecting Archean provenance of detrital material and lack of Sr isotopic homogenization since deposition. Sediment of the tuffaceous Wolverine Point Formation, near Rumpel Lake, is much more variable in Rb/Sr...

... of the Gething Formation north of the Wolverine River. The microfaunal assemblages in the Moosebar Member point to an open-marine environment in the Smoky River area changing progressively southward to a brackish-water environment in the central Foothills, and ultimately a freshwater environment at the southern...

.... The sedimentation in the Athabasca Basin is inferred to have started after ca. 1720 to 1710 Ma ( Jeanneret et al., 2017 ). A zircon U-Pb age of 1644 ± 13 Ma has been reported from locally reworked tuff layers in the Wolverine Point Formation ( Rainbird et al., 2007 ), and U-Pb ages of 1.64 to 1.61 Ga have been...

... with a moderate amount of clay intraclasts and mudstone interbeds. Sequence 3 is subdivided into the Lazenby Lake and Wolverine Point formations. The Lazenby Lake Formation, approximately 460 m thick, is further divided into the Hodge, Clampitt, Shiels, Larter, and Dowler members. The Hodge member is a very...

... of the Wolverine Lake Group that host the Wolverine deposit. A second unconformity separates the Wolverine Lake Group from overlying Pennsylvanian to Permian massive metabasalt of the Campbell Range Formation ( Murphy et al., 2006 ; Fig. 2 ). The Campbell Range Formation hosts the Cyprus-type Ice VHMS deposit...

..., Canada, were erupted or emplaced during distinct time periods (ca. 363.3, 362.8, and 355.2 Ma) in two discrete submarine basins: the Kudz Ze Kayah formation and the Wolverine Lake group. The VMS deposits in both settings are contained within intrabasinal rocks that accumulated at rapid rates of ~350...

.... The first formation constant for the SO 4 2– complex is ∼10 4.6 ( Migdisov et al., 2016 ), and although the corresponding value for the Cl – complex is about three orders of magnitude lower ( Migdisov et al., 2016 ), Cl – is highly concentrated in the Wolverine fluid. Fluoride is also known to complex...

... of the Campbell Range Formation. The mafic rocks of the Slide Mountain terrane are host to the Ice VMS deposit ( Fig. 1 ) and are interpreted to have formed in a Permian back-arc basin environment ( Plint and Gordon, 1997 ; Piercey et al., 2006 , 2012 ). The geology of the Wolverine deposit...

... to generate robust and long-lived hydrothermal systems. Thus, in ancient continental margin settings identification of HFSE-REE–enriched rhyolites may be useful in outlining potentially prospective areas for VMS mineralization. Formation of the Wolverine deposit, and other Devonian-Mississippian VMS deposits...

... is divisible into three formations from bottom to top: Wingate Sandstone (eolian), Kayenta Formation (fluvial), and Navajo Sandstone (eolian). Where fluvial Kayenta beds are absent in central Utah, the Wingate Sandstone is difficult to distinguish from the Navajo Sandstone, and the eolian package has been...

... the Wolverine succession is interpreted to represent back-arc magmatism ( Piercey et al. 2001 a ). The rocks of the Finlayson Lake district have been subjected to various degrees of deformation, but most of the deformation postdates the Devonian–Mississippian formation of the rocks of this study...

... the Wolverine deposit are very distinctive and consist of highly siliceous aphyric rhyolite flows ( Figs. 4h and 5f ) and rhyolite breccias, minor fine-grained tuffaceous rocks, interlayered with carbonaceous sedimentary rocks, iron formation, and carbonate exhalite ( Bradshaw et al., 2001 ). The aphyric...

... area with locations of Figs. 3 – 8 and locations of former lava dams. Inset shows geological and geomorphological features described in the text: TrS, Seminoff Formation; EJgA, Jurassic granodiorite and monzogranite of the Aishihk Suite; HCF, Holbrook Creek lava (below letters). DEMs prepared...

... consists of five facies associations. The Muddy Creek Formation is overlain by a newly mapped carbonate unit of uncertain age or stratigraphic assignment (white limestone “b”). The numbered tuff locations refer to tuffs mentioned and/or sampled in this study: 1) tuff of Wolverine Creek ( Castor et al. 2000...
