Marsh Foraminiferal Distribution in the Minas Basin and their Occurrence in Marsh Cores from the Region
(1983-04-15)The foraminiferal assemblages present along two Kingsport marsh surface transects were delineated into zones with respect to vertical elevation above mean sea level (a.m.s.l.), and salinities. The highest vertical zonation, ... -
The Relationship of Coastal Drumlins to Barrier Beach Formation Along the Eastern Shore of Nova Scotia
(1984-04-15)The Eastern Shore of Nova Scotia is experiencing post-glacial rise in relative sea level, resulting in a transgressive coastal environment. Drowned estuaries are fronted by eroding drumlin headlands which provide a sediment ... -
The Sedimentology of Glaciofluvial Deposits Near Upper Nine Mile River, Nova Scotia
(1984-04-15)Four sand and gravel pits east of Upper Nine Mile River expose parts of a 25 km long ridge of unconsolidated glaciofluvial sediment. Twenty five (25) stratigraphic sections were measured along fresh exposures in the ... -
Upper Paleozoic Alluvial Plain Sedimentation in the Morien Group, Eastern Cape Breton, Nova Scotia
(1984-04-15)A section of upper Morien strata located near the western margin of the Sydney Basin was examined. Three sub-assemblages of sedimentary facies were recognized: Thick bedded sandstone characterized by a fining-up ... -
Arcellaceans in Eastern Canada: Selected Biostratigraphic and Biological Studies
(1984-04-15)Arcellaceans (testate rhizopods) are considered as part of the artificial group known as "thecamoebians". Arcellaceans exist in all modern freshwater environments, and they have been found to have value as indicators of ... -
The Origin and Occurrence of Cordierite in the South Mountain Batholith
(1984-04-15)Cordierite occurs on both sides of the contact between the South Mountain batholith and the Meguma metasediments, in southwestern Nova Scotia. Textural features of the cordierites in the batholith, the xenoliths, the Meguma ... -
Infraspecific Variation in Arcellacea (Thecamoebians) from Eastern Canada and a Selected Biostratigraphic Study
(1984-04-15)Clones of several morphotypes of the arcellacean species Centropyxis aculeata (Ehrenberg) were established and the range of variation in individual clones was examined. Considerable morphological variation was noted, ... -
The Mineralogy of the Fifteen Mile Stream Gold District
(1983-04-15)Comparison of two distinct tailings piles from two separate periods of operations, reveals that they are similar in mineralogy and lithology. The proportions in which the minerals and lithic fragments are present, differs ... -
Geologic, Fluid Inclusion and Stable Isotope Study of a Carbonate-Hosted Lead Deposit at Pembroke (Glenbervie), Colchester County, Nova Scotia
(1983-04-15)The Pembroke (also Glenbervie) prospect is a carbonate-hosted lead deposit located at 45o17'05" North Latitude and 62o56'15" West Longitude in Colchester County, Nova Scotia. The deposit is stratabound within the Macdonald ... -
Compound Specific Isotope Analysis of Invertebrate Tissues: Determining Nitrogen Variability in Coastal Nova Scotia
(2020-05-15)Anthropogenic nitrogen (N) loading in coastal marine environments causes eutrophication, alters food web structures, and degrades water quality. In Nova Scotia, anthropogenic N sources are introduced to coastal waters ... -
Cooling History of a Rifted Passive Margin - New Insights from (U-Th)/He Thermochronology along the Labrador Passive Margin
(2019-05-15)The Labrador Sea is the result of rifting and breakup between Labrador and Greenland. The asymmetry of magmatism, bathymetric/topography, sediment distribution and crustal structure along both margins suggests a lithospheric ... -
Redox state of the South Mountain Batholith: A reconnaissance study using zircon geochemistry
(2019-05-15)The late Devonian South Mountain Batholith (SMB) of Southwestern Nova Scotia is the largest plutonic igneous body emplaced during the Appalachian orogeny, with a current surface expression of 73,000 km2. The batholith ... -
A Quantitative Analysis of Deglaciation as a Possible Earthquake Mechanism in Canada.
(1985-04-15)With the exception of earthquakes occurring along the Pacific coast, earthquakes in Canada cannot be explained by plate tectonic theory. Deglaciation has been proposed as a possible cause of non-tectonic Canadian ... -
Geophysical Analysis of Field and Laboratory Measurements at the Eastville Lead-Zinc Deposit Colchester County, Nova Scotia
(1985-04)A large part of the mineralization of the Meguma Group is associated with the Goldenville - Halifax Transition. This Transition zone produces geophysical anomalies. Horizontal loop E.M. surveys show a strong conductive ... -
The Contact Metamorphic Effects of a Granitoid Pluton on Zinc-Lead Mineralization in the Manganiferous Metasediments of the Meguma Group, Eastville, Colchester County, Nova Scotia
(1985-04-15)The distribution of mineral resources in the Meguma Zone has been found to be spatially associated with the transition of the Goldenville and Halifax Formations (GHT, Zentilli and MacInnis, 1984). The Eastville deposit ... -
Arcellaceans in Nova Scotia: Selected Biostratigraphic Studies
(1985-04-15)Surficial sediment samples and cores from both Albro and Penhorn Lakes were examined to determine the biostratigraphy of the lakes, based on arcellaceans. Considerable morphological variation of species is noted and ... -
The Sedimentary Environment of the Late Cretaceous St. Mary River Formation, Southwestern Alrerta
(1985-04-15)It is the purpose of this study to interpret the sedimentary environment which produced the St. Mary River Formation (SMRF) . This study attempts to expand on the preliminary sedimentological work of previous authors py ... -
The Manganiferous Slates of the Cambro-Ordovician Meguma Group at Lake Charlotte, Halifax County, Nova Scotia.
(1985-04-15)In recent years there has been considerable interest in manganiferous sediments of the oceans. This interest is due to the special environment required to form manganiferous sediments, the association with other metals, ...
