A comparison of the hydrothermal alteration systems around the Mo-hosting White Pine intrusion, Utah, and the Buckingham Porphyry, Nevada
(2015)The White Pine Fork Mo porphyry has an estimated resource of 16 Mt of Mo at 0.1% Mo. The host intrusions are K-feldspar- and quartz-porphyritic monzo- to syeno-granites characterised by LREE enrichment, fractionated HREEs ... -
Geochemistry and mineralization of the Archean Titan (Roaring River) intrusion, Thunder Bay, Ontario
(2023)The 2690 ± 3.2 Ma Titan intrusion is an approximately 7 by 3 km, roughly ovoid, mafic-ultramafic intrusion, located just north of the inferred boundary between the Winnipeg River and Marmion terranes. Outcrop in the area ... -
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 and geochemistry of the Laird Lake property and associated gold mineralization, Red Lake greenstone belt, northwestern Ontario
(2018)The Laird Lake property encompasses the tectonic contact between the Balmer (2.99 to 2.96 Ga) and the Confederation (2.74 to 2.73 Ga) assemblages on the south-western end of the Red Lake greenstone belt, Northwestern ... -
Geology and geochemistry of the Terrace Bay batholith, N. Ontario
(2019)The Terrace Bay Batholith is a 25 km long oval shaped granitoid intrusion located in the western portion of the Schreiber-Hemlo greenstone belt, part of the larger Wawa-Abitibi terrane. The pluton was emplaced at 2689±1.1 ... -
Mineral chemistry, hyperspectral analysis and applications for regional exploration at the Hemlo Gold deposit, Ontario, Canada
(2018)The Barrick Gold owned Hemlo Au deposit is a world class Archean Au deposit situated in Northern Ontario, Canada with historic production of >21 Moz of Au over 32 years of continuous operation. The deposit has a strike ... -
Petrogenesis of the ferrogabbroic intrusions and associated Fe-Ti-V-P mineralization within the McFaulds Greenstone belt, Superior Province, Canada
The McFaulds Lake area (commonly known as the Ring of Fire), has been the site of much recent exploration within northern Ontario. The area represents a recently discovered Archean greenstone belt which is host to world ... -
The structure, stratigraphy and strain history of the Seine Group and related rocks near Mine Centre, Northwestern Ontario
(1982)One or possibly two overlapping periods of deformation are responsible for the structures observed in the rocks in the Seine River area. This deformation has resulted in the formation of tight to isoclinal, non-plane ...
