Accessory rare metal mineralization in the Coldwell Alkaline Complex, Northwest Ontario
(1990)Accessory rare metal mineralization has been investigated in seven lithologies in intrusive Centres I and III of the Coldwell alkaline complex. All units contain minerals that are enriched in a suite of granitophlle ... -
Alteration and fluid characterization of the Hamlin Lake IOCG occurrence, Northwestern Ontario, Canada
(2012-11-10)The Hamlin Lake area is located approximately 120km southwest of Thunder Bay, Ontario, in the Shebandowan Greenstone Belt of the Wawa Subprovince in the Superior Province. The area has been explored for its copper and ... -
Application of a sequential partial extraction procedure to investigate uranium, copper, zinc, iron and manganese partitioning in recent lake, stream and bog sediments, northern Saskatchewan / by Douglas Andrew Warren Lehto. --
(1981)Sequential partial extractions show that partitioning of uranium, copper, zinc, iron and manganese into lake, stream and bog sediments are affected by the type and abundance of component fractions present in sediments ... -
Aspects of gallium geochemistry in upper mantle-derived lherzolite xenoliths and continental alkaline volcanic rocks
(1989)Various aspects of the geochemistry o-f Ga in upper mantle—derived garnet, Iherzolite xenoliths (from the Bult-fontein Floors mine dump in Kimberley, South Africa), spinel Iherzolite xenoliths (from Mount Porndon, ... -
Aspects of the mineralogy of the Murun alkaline complex, Yakutia, Russia
(2001)The Murun complex contains a number of unusual and mineralogically unique rocks. Many of them are problematic in terms of their genesis and petrographic interpretation. These enigmatic rocks include charoite assemblages, ... -
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 ... -
Assimilation of basic xenoliths within centre 3 syenites of the Coldwell Alkaline Complex, Ontario
(1989)This thesis describes the occurence, mineralogy and assimilation of basic Kenoliths hosted by Centre 3 syenites. Field work ‘was earned out in two locations, one in the vicinity of Neys/Ashburton and the other a ... -
Cathodoluminescence studies of feldspars and apatites from the Coldwell Alkaline Complex
(1995)The Coldwell alkaline Complex is located on the north shore of Lake Superior, and consists of three Centers representing three magmatic episodes. Center I consists of gabbro, and layered and unlayered ferroaugite syenite. ... -
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 ... -
Circum-Troodos limestone succession of south and west Cyprus : a magnetic fabric and magnetic mineralogical study
(2005)Calcite petrofabrics align easily with weak strains, possibly being the most sensitive classical petrofabric indicator. Thus, calcareous sediments may reveal stress trajectories in neotectonic environments. Calcite aligns ... -
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 ... -
Comparison of the late quaternary sedimentary sequence and paleomagnetic record of the North Bay outlet and a Baffin Island fiord
(1983)The lithology of the Late Quaternary lacustrine sequences of five lakes in the North Bay area differs from one lake to another. However, chronostratigraphically equivalent sections of cores taken from the same lake ... -
Constraints on the formation of depositional placer accumulations in coarse alluvial braided river systems
(1989)Placer accumulations are formed by the preferential sedimentation of heavy minerals from the general population of detritus being transported by a fluid. The depth, velocity, and grain size conditions under which placers ... -
Deformation of layered rocks near the Wawa-Quetico subprovince boundary / by David Lawrence Nicol
A supracrustal sequence of rocks near Manitouwadge, Ontario consists of metavolcanlc rocks, Including pillow lavas, banded iron formation, amphibolite, and a quartzofe1dspathic hornblende-blotite gneiss. This rock has ... -
Depositional environments of the 3.0 Ga. Finlayson and Lumby Lake greenstone belts, Superior Province, Ontario, Canada
(1998)The Finlayson and Lumby Lake Greenstone BeHs are located approximately 200km west of Thunder Bay, Ontario, nom of Atikokan, Ontario. Within both the Finlayson Lake and Lumby Lake Grsenstom belts two distinct sequences ... -
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, ... -
Dimensional and crystallographic fabric development in experimentally deformed synthetic aggregate and natural rocks
(1990)Calcite Portland-cement aggregate samples were deformed triaxially at 25 deg. with confining pressures of 200 Mpa. The samples were deformed under experimental approximations of pure shear (dry and wet experimental ...
