Gravitational Interpretation and Modelling of the South Mountain Batholith. Southern Nova Scotia.
(1978-03-15)Much controversy surrounds the issue of the geometry of the South Mountain Batholith of southern Nova Scotia. Gravity data released by the Department of Energy, Mines and Resources within the last year has allowed a ... -
Depositional Analysis of a Section of the Lower Meguma (Lower Paleozoic), Ship Harbour, Nova Scotia
(1978-03-15)A section of the lower Meguma (Lower Paleozoic) near Ship Harbour, Nova Scotia, was examined in detail in terms of bed thickness, sedimentary structures and grain size. Interpretation of depositional processes and ... -
Metamorphism of the George River Group; Gold Brooks, Victoria County, Cape Breton Island, Nova Scotia.
(1979-03-15)The Precambrian George River Group of Cape Breton Island, Nova Scotia is characterized by metasediments and metavolcanic rock types. A sequence of predominantly feldspathic quartzites slates and quartzites at Gold Brooks ... -
Stratigraphy and Depositional Environment of the Meaghers Grant Formation of the Musquodoboit Valley, Central Nova Scotia.
(1978-03-15)The Meaghers Grant Formation is a Lower Carboniferous siliclastic sequence in the Musquodoboit Valley of central Nova Scotia. It has been studied in outcrop and mainly in core. It lies wholly within the Lower Windsor Group ... -
Mode of Extrusion of Frenchman's Barn, Dunn Point Volcanic Formation, Arisaig, Antigonish County, Nova Scotia.
(1979-03-15)Frenchman's Barn, near Arisaig, Nova Scotia, is an enigma. It contains some of the textural characteristics of ash flows and lava flows and some which are not common to either. Part of the problem is that many of the ... -
A Study of the Rare Earth Element Geochemistry and Mineral Chemistry of the Anorthosites and Related Rocks near Pleasant Bay, Cape Breton Island, Nova Scotia
(1979-03-15)The anorthosites and related rocks of this study are located about 5 kilometres east of the village of Pleasant Bay, Cape Breton Island, Nova Scotia. The anorthosites outcrop as a thin (~900m), northeast-trending lens with ... -
Environmental Interpretation of the Upper 3C, the 4R, and the Lower 4E Member a of the Helikian-Aged Parry Bay Formation, Bathurst Inlet, N.W.T.
(1979-03-15)A stromatolitic, clastic, dolomite-mudstone section, within the central portion of the Parry Bay Formation, Bathurst Inlet, N.W.T., is described. The section is divided into seven lithological units, each of which are ... -
Experimental Investigations of Viscous Remanent Magnetization Using a Continuous Measurement System
(1979-03-15)This study showed that with a simple circuit modification this new continuous measurement system of viscous remanent magnetization (VRM) can be made more flexible as a far as the magnitude of the applied field and VRM ... -
A Study of some Trace Metals in Surface and Ground Waters at Bridgewater, Nova Scotia
(1978-03-15)Much controversy has arisen concerning the water quality in an area northwest of Bridgewater, Nova Scotia. To resolve the problem, water samples were taken and analyzed for trace metals, from the area which was also ... -
Occurrence and Origin of Garnet in the South Mountain Batholith
(1980-03-15)Garnet occurs around the margin of the South Mountain batholith as an accessory mineral in three distinct comagmatic phases. Electron microprobe analyses and textural relationships of 50 garnet-biotite pairs indicates that ... -
A Field Geological Study and Analysis of Joint Patterns Related to the Francoeur-Arntfield (Gold Mines) Shear Zone, Beauchastel Township, Temiscamingue County, Abitibi Greenstone Belt, Quebec.
(1980-03-15)Field mapping (1:5000) and study of joints in an area of 7.3 square kilometres centered around the Arntfield Gold Mines, during the summer of 1979, forms the basis for this study. East-striking, north-dipping rocks of ... -
Fluid Inclusion Geothermometry in Fluorite from Gays River, Nova Scotia and Boat Harbour, Newfoundland
(1980-03-15)Fluid inclusions in post-ore fluorite from the base metal deposit in Carboniferous carbonates at Gays River, Nova Scotia, homogenize at a mean temperature of 142 + 8oC. Calcite in the deposit crystallized earlier, at a ... -
The Petrography and Depositional Environment of the Cardium Formation in the Rocky Mountain House Area of Central Alberta
(1980-03-15)The Cardium Sandstone in the Rocky Mountain House area of the Garrington and Ferrier fields of Alberta is part of a progradational sequence consisting of marine shale at the base through sandstone to conglomerate, followed ... -
Heavy Mineral Provenance Studies on the Wallace River Formation of the Pictou Group between Tatamagouche and River John, Nova Scotia
(1980-03-15)Heavy mineral provenance studies were conducted on sandstones of the Wallace River Formation (Pictou Group) over an area of roughly 200 km2. As well, three major heavy mineral provinces were established. The strata cropping ... -
40Ar/39Ar Dating of Silurian-Devonian Rocks from the Gander and Botwood Zones of Newfoundland and their Paleomagnetic Implications
(1980-03-15)Paleomagnetic poles recently reported by Lapointe, Murthy, and others are widely divergent from poles of similar age from cratonic North America. Two of the units from Newfoundland have each yielded two widely separated ... -
Post-Pleistocene Sea Level Changes in the Baie Verte Estuary (Northumberland Strait) as Revealed by Foraminiferal Studies
(1980-03-15)Two cores were obtained from the Baie Verte estuary of the Northumberland Strait to study relative sea level changes by examination of foraminiferal distributions. The base of the cores contained a layer of salt marsh ... -
