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 and alteration associated with the Hamlin Lake VMS system, Shebandowan Greenstone belt, Northwestern Ontario, Canada
(2008)
The Hamlin Lake area is located approximately 120 km southwest of the City of Thunder Bay, Ontario within the Shebandowan greenstone belt of the Wawa Subprovince, Superior Province. The purpose of this study was to understand ...
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, ...

(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 ...
Whole rock geochemistry, mineral chemistry, petrology and Pt, Pd mineralization of the Seagull Intrusion, Northwestern Ontario
(2005)
The Seagull Intrusion emplaced during formation of the 1.1 Ga Mid-continental Rift centred around Lake Superior was studied in several drill core and surface samples and consists of a lower ultramafic section (~650 m) and ...
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 ...
