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 ... -
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 ... -
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 ... -
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 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 sequence stratigraphy of the paleoproterozoic Rove and Virginia formations, southwest Superior Province
(2006)The Paleoproterozoic Rove and Virginia Formations are lithostratigraphically and chronostratigraphically correlative units which comprise the upper sedimentary strata in the Animikie basin. They sharply overlie an intensely ... -
Sedimentology and stratigraphy of the northern and central metasedimentary belts in the Beardmore-Geraldton area of northern Ontario
(1987)The northern and central metasedimentary belts (NMB, CMB) are east-trending, regional (formation- to group-scale) iithostratigraphic units within the Beardmore-Geraldton Archean terrane of northern Ontario's Superior ... -
Sibley Group : a lithostratigraphic, geochemical, and paleomagnetic study
(2003)The Sibley Group is an unmetamorphosed Mesoproterozoic red bed sequence, commonly flat lying, that formed in an intracratonic basin between 1450 Ma and 1500 Ma. It covers an area o f 15,000 km^, and reaches a total ... -
Stratigraphic architecture of a paleoproterozoic iron formation depositional system : the Gunflint, Mesabi and Cuyuna iron ranges
(1996)Understanding iron formation depositional processes has been hindered by the lack of precise modern analogues. However, by combining a regional basin analysis of sedimentary and volcanic rocks surrounding an iron formation ... -
Stratigraphy of two late paleozoic basins : implication for the timing of final emplacement of the Meguma terrane
(1990)Paleoraagnetic studies indicate the Meguma terrane's final emplacement occurred between the Mid-Devonian and Early Permian. Lithostratigraphic units near the boundary of the terrane were investigated in order to provide ...
