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 ... -
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 ... -
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 ... -
Magnetic fabrics and boundary structure at the Quetico - Shebandowan subprovince boundary, near Kashabowie, NW Ontario
(1990)The Quetico metasedimentary subprovince and the volcanic-plutonic Shebandowan belt to the south meet along an east-west steeply dipping boundary that is believed to have been affected by dextral transpressional deformation. ... -
The magnetic fabrics and strain history of the Achean Seine Group metasedimentary rocks near Mine Centre, Northwestern Ontario
(1992)The Seine Group metasedimentary rocks are situated between two converging major dextral transcurrent faults, the Quetico Fault to the north and the Seine River Fault to the south. To the west lies the Bad Vermillion ... -
Magnetic fabrics from sheeted dikes reveal regional magma flow patterns, and the spacing and dimensions of ophiolite magma-chambers, Troodos ophiolite, Cyprus
(2002)Orientation-distributions of crystals were determined for 1289 specimens of the Sheeted Dike Complex of the Troodos ophiolite, located on the island of Cyprus. These were inferred from anisotropy of magnetic susceptibility ... -
Magnetic fabrics of granitic plutons and gneisses, Northwestern Ontario
(2004)Specimens of plutonic granitic gneisses have been collected from different locations of the Superior Province. The study of their Koenigsberger ratio (related to natural remanent magnetization) and the theoretical ... -
Neo-tectonic and rock magnetic study of the Circum Troodos Sedimentary Succession, Cyprus
(1999)The Circum Troodos Sedimentary Succession (Late Cretaceous to Recent) overlies the Troodos ophiolite of Cyprus, located in the Eastern Mediterranean. The pattern of neo-tectonic deformation was investigated through ... -
Paleomagnetic secular field variation and rock magnetism of some early holocene (<9900BP) postglacial lacustrine sediments near Thunder Bay, Northwestern Ontario, Canada
(2006)Paleosecular magnetic changes through a 1.5m section of post-glacial lacustrine deposits are strongly influenced by mineralogy and differential compaction. The sediments chiefly comprise clay and, in the lower one third ... -
Paleomagnetism, structure and magnetic fabrics in a traverse of the Quetico subprovince between Atikokan and Kashabowie, NW Ontario
(1993)The metasedimentary rocks along the traverse reveal low to high grade metamorphism from chlorite schist near Atikokan, through biotite schist to migmatites in the west within the centre of the Quetico Belt. Continuing ... -
Quetico Fault in the Superior Province of the southern Canadian Shield
(1984)The Quetico fault is a major transcurrent fault in the southern Superior Province of the Canadian Shield. Along part of its length the fault forms the boundary between the Wabigoon subprovinces. Dextral motion on the ... -
Rock magnetic and structural investigation of the Moss Lake stock and local area : western Shebandowan belt
(1995)The thesis area is located 120 km west of the City of Thunder Bay, Ontario, straddling the contact of the Quetico and Wawa subprovinces of the Archean Superior Province. Metasedimentary rocks of the Quetico Subprovince ... -
Rock magnetic studies of the CY-4 drillhole through the Troodos ophiolite, Cyprus
(2006)Rock magnetic properties of 50 specimens from a continuous section through the lower layers of the Troodos ophiolite in the CY-4 drill hole, reveal an alteration and palaeomagnetic history consistent with ocean spreading. ... -
Stratigraphy, structure and metamorphism of Archean rocks at Rainy Lake, Ontario
(1980)The rocks of the Rainy Lake area have been deformed during three distinctive episodes. Minor structures provide the geometry which characterizes each episode. The youngest structures include regional faults, a crenulation ... -
Structure and magnetic fabric of the Quetico metasedimentary rocks in the Calm Lake - Perch Lake area, near Atikokan, Northwestern Ontario
(1987)The Quetico metasedimentary rocks are the metamorphosed equivalents of a turbidite sequence, comprised of a repetative interstratification of sandstones and mudstones. The rocks are metamorphosed to lower greenschist ... -
The structure, stratigraphy and strain history of the Seine Group and related rocks near Mine Centre, Northwestern Ontario
(1982)One or possibly two overlapping periods of deformation are responsible for the structures observed in the rocks in the Seine River area. This deformation has resulted in the formation of tight to isoclinal, non-plane ... -
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 ... -
Theoretical and experimental investigation of pressure solution
Consideration of the existing thermodynamic theory of pressure solution (PS) shows that this theory is applicable to the development of PS structures as well as to local grain-scale diffusive transfer. Local precipitation ...
