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. ...
An investigation on the control of gold mineralization in the Beardmore-Geraldton greenstone belt and surrounding Quetico-Wabigoon subprovince boundary area
(2014-01-22)
The Beardmore-Geraldton greenstone belt is located along the boundary between the Wabigoon and Quetico subprovinces in the Superior province of the Canadian Shield. Historical gold mines and current gold exploration camps ...
Macro- and micro-structure comparison of ancient and modern iron-rich stromatolites
(2015)
The Gunflint and Biwabik Formations comprise the middle units of the Paleoproterozoic Animikie Group that crop out near the northwestern shore of Lake Superior. Stromatolitic units were investigated and sampled at 9 outcrop ...
The mineralogy and petrology of layered series nepheline syenite within Center II of the Coldwell Complex
(2018)
The Coldwell Complex is situated within the Archean Schreiber-White River
metavolcanic and metasediment of the Superior Province. Spanning over 25km in diameter, it is
the largest alkaline intrusion in North America. The ...
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 ...
Design and testing of a permeable reactive barrier system for treatment of sulphate rich waters at the former steep rock iron mine, Atikokan, Ontario
(2015)
Acid mine drainage (AMD) is one of the greatest challenges facing the mining industry globally. Methods for addressing this issue have been widely studied; however, few studies have addressed sites with a less common water ...
Characterization of the MAX porphyry Mo deposit using trace element geochemistry in hydrothermal alteration minerals, Trout Lake, B.C.
(2016)
Over the last few decades it has become increasingly difficult to discover new ore
deposits and as existing deposits are exhausted, techniques for improving exploration success are
becoming vital. In this study I ...
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 ± ...
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 ...
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 ...
