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 ... -
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, ... -
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. ... -
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 ... -
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 ... -
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 ... -
Geochemistry and PGE mineralization of the Kitto intrusion : a product of Mesoproterozoic plume magmatism through fault bounded archean crust, East Nipigon Embayment, Northern Ontario
(2007)The Kitto intrusion is a Mesoproterozoic 1117.7 ±1.8 Ma peridotitic to gabbroic intrusion, that formed as a result of plume magmatism and was emplaced along Mesoproterozoic and Archean faults in the East Nipigon Embayment ... -
Geology and alteration associated with the Hamlin Lake VMS system, Shebandowan Greenstone belt, Northwestern Ontario, Canada
(2008)The Hamlin Lake area is located approximately 120 km southwest of the City of Thunder Bay, Ontario within the Shebandowan greenstone belt of the Wawa Subprovince, Superior Province. The purpose of this study was to understand ... -
Geology of sulphide-facies iron-formations and associated rocks in the lower Steel River-Little Steel Lake area, Terrace Bay, Ontario
(1987)The Lower Steel River - Little Steel Lake area is located about 25 km east of Terrace Bay, Ontario. Seventeen iron-formations were investigated within this metamorphosed Archean volcanic and sedimentary terrain, which ... -
Geology, petrology, geochemistry and platinum-group element-gold-copper-nickel ore asselmblage [i.e. assemblage] of the Roby Zone, Lac Des Iles Mafic-Ultramafic Complex, Northwestern Ontario
(1998)The Archean Lac des lies Complex is a mafic to ultramafic intrusion emplaced into gneissic tonalite. The Lac des lies Complex Is the largest of several mafic to ultramafic intrusions that form a circular outcrop pattern ... -
Granitoids and rare-element pegmatites of the Georgia Lake area, northwestern Ontario
(1985)The Georgia Lake pegmatite field is located in the Quetico Gneiss Belt of the Superior Province. Spodumene-bearing and subordinate beryl-bearing pegmatites of the Georgia Lake area are flanked to the south and east by ... -
Gravity study of an Archaen crustal segment near Thunder Bay, Ontario
(1982)A gravity survey in an area involving portions of the Quetico and Shebandowan subprovinces of the Superior structural province resulted in the establishment of 350 new gravity stations in addition to 50 previously ... -
An investigation of the use of anisotropy of complex magnetic susceptibility to analyse strain in experimentaly deformed materials and massive sulphides
(1991)Anisotropy of magnetic susce:ptibility (AivJS) has become a widely accepted method of fabric analysis in rocks, especially those which have been deformed tectonically. The use of anisotropy of complex magnetic suscepti ...
