Assessment of permeable reactive barriers for sulphate reduction at the former Steep Rock Iron Mine site, Atikokan, Ontario
(2012-11-10)This study assessed if a permeable reactive barrier (PRB) could be used to reduce sulphate and metal concentrations in Hogarth pit lake, a sulphate-toxic (up to 2,000 mg/L) pit lake at the former Steep Rock iron mine in ... -
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 ... -
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 ... -
Depositional processes operating on the paleoproterozoic gowganda ice margin
(2014-01-22)Glacial sedimentary rocks of the Huronian Supergroup crop out along the north shore of Lake Huron and were likely deposited on what is thought to have been a divergent continental margin (Fralick and Miall, 1981; 1989). ... -
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 ... -
Diamondiferous mass-flow and traction current deposits in a Neoarchean Fan Delta, Wawa area, Superior Province
(2012-11-10)Diamond bearing Neoarchean metaconglomerates are present in the Michipicoten greenstone belt, Wawa-Abitibi subprovince near Wawa, Ontario. They form a portion of the Dore Metasedimentary rocks in the Arliss Lake subbasin, ... -
Distribution and chemistry of kimberlite indicator minerals in the southern Slave Province, NWT
(2020)As part of the greater Slave Province geophysical, surficial materials and permafrost study, a Northwest Territories Geological Survey (NTGS) led government-academic-industry research program, this study is intended to ... -
Effects of a second wood ash application to soil on Picea mariana (Mill.) B.S.P. and Picea glauca (Moench) voss growth and foliar nutrition and soil chemistry
(2022)As the Canadian biomass energy sector grows, so too does its production of by-products such as wood ash from the combustion of wood biomass for energy. Wood ash can be land applied with the goal of increasing the ... -
Environmental control of seawater geochemistry in a Mesoarchean Peritidal System, Woman Lake, Superior Province
(2020)The 2.857±5 Ga (this study) carbonate platform at Woman Lake, Ontario, Canada, presents a unique opportunity to fill a 130 million year knowledge gap on early carbonate sedimentology and ocean chemistry between similar ... -
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 ... -
Geochemistry and Au mineralization within the Kakagi-Rowan Lakes greenstone belt : a study of the Angel Hill Gold Zone
(2012-11-10)The Angel Hill Gold Zone of the West Cedartree Gold Project has been exposed over 300 meters along the internal contact of ultramafic and gabbroic rocks within the Kakagi Sill. The sill lies within the Kakagi-Rowan Lakes ... -
