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 ...
Study of zonation at the Nanisivik Zn-Pb-Ag mine, Baffin Island, Canada
(1985)
Zn-Pb-Ag mineralization at Nanisivik, northwest
Baffin Island, is hosted by Proterozoic, laminated dolostone
of the Society Cliffs Formation. Mineralization of the Main
Orebody is highly variable in terms of texture and ...
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 ...
Tectonic magnetic fabrics in pure and simple shear : experimental investigations
(1988)
Triaxial compression tests were preformed such that
changes in the magnetic susceptibility anisotropy with strain
would be represented by experimental approximations of simple
shear and pure shear. Both types of tests ...
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 ...
Sedimentology and stratigraphy of the northern and central metasedimentary belts in the Beardmore-Geraldton area of northern Ontario
(1987)
The northern and central metasedimentary belts (NMB,
CMB) are east-trending, regional (formation- to group-scale)
iithostratigraphic units within the Beardmore-Geraldton
Archean terrane of northern Ontario's Superior ...
Survey of the mainland and island belts, Thunder Bay Silver District, Ontario : fluid inclusions, mineralogy, and sulfur isotopes
(1987)
The Thunder Bay Silver District is composed of two
curvilinear groups of veins, the Mainland and Island Belts. The
veins can be mineralogically divided into the barren, silverbearing,
and 5-element association veins.
During ...
Petrography, geochemistry and petrogenesis of alkaline dyke rocks from the Coldwell Alkaline Complex, Northwestern Ontario
(1988)
Dyke rocks occurring in the Coldwell alkaline instrusive complex, N. W. Ontario, were studied by various petrographic and geochemical means. The resulting observations indicate that 5 types of mafic alkaline lamprophyres, ...
Petrology of syenites from centre III of the Coldwell Alkaline Complex, Northwest Ontario
(1988)
The Coldwell Alkaline Complex, situated on the north shore of Lake
Superior, is of Neohelikian age. It is intruded into Archean supracrustal
rocks of the Superior Province, near Marathon, Ontario. The complex has a
diameter ...
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, ...
