A Study of Carbonate Rocks From the Late Visean to Namurian Mabou Group, Cape Breton Island, Nova Scotia
(1995-04-15)The Late Visean to Namurian Mabou Group of Cape Breton Island conformably overlies the marine to non-marine Windsor Group and unconformably to conformably underlies the fluviatile Cumberland Group. It represents the first ... -
Structural Geology of the Meguma Group Adjacent to the Eastern Contact of the South Mountain Batholith
(1995-04-15)The purpose of this study is to recognize and evaluate structural features that may be related to the emplacement of the South Mountain Batholith. The Acadian orogeny produced folds within the Meguma Terrane with a north-east ... -
Foraminiferal Assemblages From a Sediment Core From the Inner Scotian Shelf: Implications for Till-Tongue Stratigraphy and Paleoceanography
(1995-04-15)The inner Scotian Shelf juxtaposes the Nova Scotia coastline, ending at the 100 m bathymetric contour, and consists of several zones based on seismic sequences and sea-bottom morphology. At the maximum extent of the last ... -
Structure of Bedrock Offshore From Point Aconi, Cape Breton Island, Nova Scotia
(1995-04-15)The Prince Colliery is a major offshore coal mine operated by the Cape Breton Development Corporation (DEVCO) in the Hub coal seam of the Sydney Mines Formation (Upper Carboniferous). This thesis presents the results of a ... -
Magnetic Susceptibility of Halifax Formation Slates at the Halifax International Airport: Correlation with Potential for Acid Drainage
(1995-04-15)The disruption by excavation or quarrying of sulphide-rich slate units of the Halifax Formation of the Meguma Group of Nova Scotia leads to oxidation of the sulphides and generation of acid drainage. Construction within ... -
Marginal Marine Foraminifera and Thecamoebians in the Upper Cretaceous to Eocene Deposits of the South-Central Pyrenees, Spain
(1995-04-15)The Upper Cretaceous to Eocene marginal marine sediments, in the northeastern Pyrenees of Spain, is a classic area in which to study sequence stratigraphy. Sequence stratigraphy requires strong sea-level control. The ... -
Comparison of Dikes and Screen Units Within the Transition Zone From Extrusives to Sheeted Dikes of the Troodes Ophiolite, Cyprus
(1995-04-15)Petrological and geochemical investigations of a series of interleaved dikes and lava screens from the Transition Constructional Zone of the Troodos ophiolite are studied to determine whether differences in magnetization ... -
Fluid inclusions and microstructure of flexural-slip bedding-concordant veins within the Ovens Anticline, Lunenburg, Nova Scotia
(1996-04-15)Fluid inclusions and microstructure of flexural-slip bedding-concordant quartz veins (FSBCVs) from the Ovens Anticline of the Meguma Group, were assessed and provide data on conditions and mechanisms of flexural-slip ... -
Apatite fission track study of tectonics and provenance of sediments in the Sawtooth Range, Sverdrup Basin, Canadian Arctic Archipelago
(1996-04-15)The Sverdrup Basin in the Canadian Arctic is a large intracratonic rift basin initiated during the late Paleozoic. Its sediments were deposited in two sequences: Proterozoic to mid-Paleozoic deformation in the Ellesmerian ... -
Interpretation and modelling of gravity data within the Meguma Terrane, central Nova Scotia
(1996-04-15)Gravity methods can be used to identify geological features that exhibit sufficient density contrasts with the surrounding country rock. Collection and reduction of new gravity data in central Nova Scotia, combined with ... -
Paleotectonic setting of the Takla Group volcano-sedimentary assemblage, Stikine Terrane, McConnell Creek map area, north central British Columbia
(1996-04-15)The Upper Triassic Takla Group volcano-sedimentary assemblage is located within the Stikine Terrane of the Intermontane Belt in the Canadian Cordillera. In the McConnell Creek area, the assemblage consists of clinopyroxene ... -
Deformation and metamorphism in the contact aureole of the S. Mt. Batholith, Bedford area
(1996-04-15)This study documents structures related to Halifax Pluton emplacement, in the Bedford area. Intrusion of the Devonian South Mountain Batholith caused both metamorphism and deformation of the Cambrian-Ordovician Meguma ... -
The Highway 101 Landfill - what have we learned?
(1996-04-15)The Highway 101 Landfill between Upper Sackville and Mount Uniacke, Nova Scotia has been in operation since 1977. Hydrochemical tests were routinely collected on 63 monitoring wells located at various depths in and around ... -
ENVIRONMENTAL DEGRADATION IN HALIFAX HARBOUR: AN HISTORICAL PERSPECTIVE USING BENTHIC FORAMINIFERA
(1996-04-15)Foraminiferal assemblages foro sediment surface samples collected in Bedford Basin, ·Halifax Harbour, in August 1992, have been investigated and compared to foraminiferal data from 1970 to determine faunal changes resulting ... -
Pyrrhotite composition and its relationship to acid drainage potential in the Halifax Formation, Meguma Group, Nova Scotia
(1996-04-15)The physical disruption of sulphidic slates of the Halifax Formation of the Meguma Group in Nova Scotia, leads to oxidation of sulphides and the generation of acid rock drainage (ARD). Acid runoff has been a serious problem ... -
Cretaceous marginal marine and freshwater rhizopods from central Nova Scotia, Canada
(1996-04-15)This study of rhizopod assemblages, from two cores drilled near Shubenacadie, provides evidence for a marine connection to central Nova Scotia during the early Cretaceous. Five different rhizopod assemblages have been ... -
THE JOGGINS AND SPRINGHILL MINES FORMATIONS FACIES MODEL AND INTERPRETATION OF THE PALED-ENVIRONMENT
(1998-04-15)The type section of the Joggins Formation is located along the eastern shore of Chignecto Bay, Nova Scotia. A bed-by-bed measurement of the Carboniferous strata within a 200m stratigraphic zone encompassing the Joggins ... -
ENVIRONMENTAL EFFECTS OF THE OLD DUNBRACK MINE DUMP, MUSQUODOBOIT HARBOUR, NOV A SCOTIA
(1998-04-15)The Dunbrack Pb-Cu-Zn prospect, located 5 km north of Musquodoboit Harbour and 45 km east ofHalifax, Nova Scotia, ceased operations in 1920. The Devonian Musquodoboit Batholith hosts the minerals in a ca. 300 Ma quartz ... -
