Petrology of ijolites from the Prairie Lake carbonatite complex
(2019)This study investigates the major and trace element composition of minerals of the ijolite series rocks occurring at the Prairie Lake carbonatite complex, northern Ontario, together with comparative data for ijolites from ... -
Petrology of syenites from centre III of the Coldwell Alkaline Complex, Northwest Ontario
(1988)The Coldwell Alkaline Complex, situated on the north shore of Lake Superior, is of Neohelikian age. It is intruded into Archean supracrustal rocks of the Superior Province, near Marathon, Ontario. The complex has a diameter ... -
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) ... -

(1989)PGE-bearing Geordie Lake intrusion is located in the north-central region of the Coldwell comples near the town of Marathon. -
The petrology, mineralization and regional context of the Thunder mafic to ultramafic intrusion, Midcontinent Rift, Thunder Bay, Ontario
(2015-06-15)The 1108 Ma Thunder mafic to ultramafic intrusion is a small, 800 x 100 x 500 m, Cu- PGE (platinum group element) mineralized body, located on the outskirts of Thunder Bay, Ontario, and associated with the early magmatic ... -
PGE–Cu–Ni sulfide mineralization of the mesoproterozoic Escape intrusion, northwestern Ontario
(2023)The Escape intrusion is a tabular to bladed, mafic–ultramafic chonolith that hosts economic concentrations of PGE–Cu–Ni magmatic sulfide mineralization. The Mesoproterozoic intrusion is located about 50 km northeast of ... -
The phase behaviour of isopropanol/water/NaCl mixtures at atmospheric pressure
(2023)Alcohol-based biofuels will play a key role in substituting the fossil fuels used in transportation and power generation. Compared to fossil fuels, alcohol-based biofuels have a lower carbon footprint and can be produced ... -
Phenology, growth and physiological responses to photoperiod and elevated [CO2] of boreal white birch (Betula papyrifera Marsh): implications to climate change-induced northward migration
(2019)With the increase in average global temperature due to rising atmospheric carbon dioxide concentration ([CO2]), rapid shifts of climate envelopes are expected to lead to norward migration for boreal tree species. As a ... -
Phenotypic variation in cone and needle characters of Pinus banksiana Lamb. (jack pine) in Northwestern Ontario
(1990)To assess the patterns of phenotypic variation in cone and needle characters of jack pine relative to spatial, climatic and ecological data, collections were made from ten trees in each of 64 sites in northwestern ... -
Phenotypic variation in Larix lyallii and relations in the larch genus
(1988)Larix Iyallii Parl, (alpine larch) is a small to medium tree restricted to the timberline zone of the mountainous regions of the Pacific Northwest of the United States and the adjacent southwest of Canada. To examine ... -
Photo-induced reactions of a photochromic fulgide in polymer matrices and in solvents
