Constraints on the formation of depositional placer accumulations in coarse alluvial braided river systems
(1989)Placer accumulations are formed by the preferential sedimentation of heavy minerals from the general population of detritus being transported by a fluid. The depth, velocity, and grain size conditions under which placers ... -
Depositional environments of the 3.0 Ga. Finlayson and Lumby Lake greenstone belts, Superior Province, Ontario, Canada
(1998)The Finlayson and Lumby Lake Greenstone BeHs are located approximately 200km west of Thunder Bay, Ontario, nom of Atikokan, Ontario. Within both the Finlayson Lake and Lumby Lake Grsenstom belts two distinct sequences ... -
Depositional processes operating on the paleoproterozoic gowganda ice margin
(2014-01-22)Glacial sedimentary rocks of the Huronian Supergroup crop out along the north shore of Lake Huron and were likely deposited on what is thought to have been a divergent continental margin (Fralick and Miall, 1981; 1989). ... -
Diamondiferous mass-flow and traction current deposits in a Neoarchean Fan Delta, Wawa area, Superior Province
(2012-11-10)Diamond bearing Neoarchean metaconglomerates are present in the Michipicoten greenstone belt, Wawa-Abitibi subprovince near Wawa, Ontario. They form a portion of the Dore Metasedimentary rocks in the Arliss Lake subbasin, ... -
Environmental control of seawater geochemistry in a Mesoarchean Peritidal System, Woman Lake, Superior Province
(2020)The 2.857±5 Ga (this study) carbonate platform at Woman Lake, Ontario, Canada, presents a unique opportunity to fill a 130 million year knowledge gap on early carbonate sedimentology and ocean chemistry between similar ... -
Formational processes of recent, arsenic rich, ferromanganese lacustrine precipitates in Nova Scotia and Northern Ontario
(2014-01-22)Banded iron - and manganese - rich precipitates were collected from the lake bottoms of Lake Charlotte (Nova Scotia), Lake Shebandowan (Ontario) and Sowden Lake (Ontario). Investigations of study areas at the macro, meso ... -
Geochemistry of shallow and deep water archean meta-iron formations and their post-depositional alteration in western Superior Province, Canada
(2018)One purpose for studying banded meta-iron formations is to determine the chemical composition of seawater in the Archean ocean and the oxygen content of the Archean oceanic-atmospheric system. Geologists use the geochemistry ... -
Geology of sulphide-facies iron-formations and associated rocks in the lower Steel River-Little Steel Lake area, Terrace Bay, Ontario
(1987)The Lower Steel River - Little Steel Lake area is located about 25 km east of Terrace Bay, Ontario. Seventeen iron-formations were investigated within this metamorphosed Archean volcanic and sedimentary terrain, which ... -
Lithogeochemistry of the sedimentary stratigraphy and metosomatic alteration in the Musselwhite gold deposit, North Caribou Lake belt, Superior province, Canada : implications for deposition and mineralization
(2008)The Musselwhite gold deposit, 100% owned and operated by Goldcorp Inc., has cumulatively produced in excess of 2 million ounces since opening in 1997 and has a projected mine life through 2013. It is situated in the North ... -
Lithostratigraphy and provenance of the Neoarchean McKellar Harbour Sequence, Superior Province, Ontario, Canada
(1995)The McKellar Harbour Sequence is located on the shore of Lake Superior approximately 40 km west of the town of Marathon, Ontario. The Sequence was examined in detail through stratigraphic and geochemical investigations ... -
Macro- and micro-structure comparison of ancient and modern iron-rich stromatolites
(2015)The Gunflint and Biwabik Formations comprise the middle units of the Paleoproterozoic Animikie Group that crop out near the northwestern shore of Lake Superior. Stromatolitic units were investigated and sampled at 9 outcrop ... -
Neoarchean coastal sedimentation in the Shebandowan Group, Northwestern Ontario
(1996)The study interpreted depositional environments from sedimentological data present in metasedimentaiy rocks of the Neoarchean Shebandowan Group of the Wawa Subprovince. Outcrops in the study area contained sedimentary ... -
Paleoproterozoic snowball earth? Sedimentology and geochemistry of a Huronian glacial cycle
(2019)The study discusses new sedimentological and geochemical results for the Paleoproterozoic Bruce glacial cycle, which represents the second of three glacial cycles within the Huronian Supergroup. This Bruce glacial event ... -
Quaternary sedimentology east of Thunder Bay, Ontario; implications for five Paleoindian sites
(2014-01-22)A geoarchaeological investigation was north of Highway 11/17, 34km east of Thunder Bay, Ontario. Five archaeological sites (Mackenzie 1, Mackenzie 2, RLF, Woodpecker 1, and Woodpecker 2) and seven additional sediment exposures ... -
Sedimentation models for glacial deltaic successions in the Thunder Bay area
(1991)The comparison of three mapped successions in northern Ontario to glacial deltas reviewed in the literature results in the definition of four end-member depositional environments for glacial deltaic sedimentation. Similar ... -
Sedimentology and Geochemistry of Regressive and Transgressive Surfaces in the Gunflint Formation, Northwestern, Ontario
(2016)The 1.878 Ga Gunflint and equivalent iron formations of the Animikie Basin were deposited during the period after the rise in atmospheric oxygen during the Great Oxidation Event, which began at approximately 2.4 Ga. The ... -
Sedimentology and geochemistry of the 2.93 Ga Basinal Facies of the Red Lake carbonate platform
(2019)The Mesoarchean Red Lake carbonate platform is the oldest (~2.93 Ga) known carbonate platform on Earth. It is comprised of a variety of chemical sedimentary rocks including: limestone, dolostone, chert, oxide iron formation, ... -
Sedimentology and geochemistry of the Mesoproterozoic Pass Lake and Rossport formations, Sibley group
(2006)The Sibley Group is an essentially unmetamorphosed, Mesoproterozoic sedimentary succession consisting of a mixture of siliciclastic and chemical sedimentary rocks. This study examined the sedimentology and geochemistry ... -
Sedimentology and paleogeographic reconstruction of the strata in and adjacent to the Sudbury impact layer in the northern Paleoproterozoic Animikie basin
(2016)The Sudbury Impact Layer (S.I.L.) is dated at 1850 Ma and is located between the underlying Gunflint Formation, with an age of 1878±1 Ma that was obtained from zircons in a tuffaceous zone approximately 105 meters below ... -
