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 ...
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 ...
Geology, geochemistry and geochronology of the Hemlo East property, Schreiber-Hemlo Greenstone Belt, Ontario
(2014-01-22)
The Hemlo East property is located approximately 50 kilometres east of the
town of Marathon, Ontario and is situated within the Schreiber-Hemlo greenstone belt
of the Wawa-Abitibi Terrane of the Archean Superior Province. ...
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, ...
Magmatic evolution and alteration geochemistry of the Black Mountain Southeast porphyry copper-gold deposit, Baguio mineral district Luzon, Philippines
(2012-11-10)
The Black Mountain porphyry Cu-Au deposit is located in the central-western portion of the Baguio mineral district, Philippines, approximately six kilometers southwest of Baguio City in the Upper Bued River. It consists ...
Seafloor deposit models, geochemistry, and petrology of the mafic-ultramafic hosted Big Lake VMS occurrence, Marathon, Ontario
(2010)
The Big Lake volcanogenic massive sulphide (VMS) occurrence, located in the Schreiber-Hemlo belt of the Superior Province, was discovered in March 2006 near Marathon, Ontario. It is hosted in a mafic-ultramafic metavolcanic ...
Petrology of the Crystal Lake Gabbro and the Mount Mollie Dyke, Midcontinent Rift, Northwest Ontario
(2018)
The Crystal Lake Gabbro (CLG) is a Y-shaped, up to 750 m wide, layered mafic intrusion with a 5 km long northern limb and a 2.75 km long southern limb, with localized Cu-Ni and Cr mineralization. The Mount Mollie Dyke (MMD) ...
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 ...
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 ...
Geochemistry and petrography of the ultramafic metavolcanic rocks in the eastern portion of the Shebandowan greenstone belt, Northwestern Ontario
(2018)
The 2.7 Ga Shebandowan greenstone belt in the Wawa-Abitibi terrane
contains unusual ultramafic rocks. The two main assemblages present within the
study area are the Greenwater and Shebandowan assemblages. The 2719.7 ± ...
