(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 ... -
SEDIMENTOLOGY, FACIES SUCCESSIONS AND CYCLICITY OF A SECTION OF THE JOGGJNS FORMATION, JOGGINS, NOV A SCOTIA
(1998-04-15)The Joggins cliffs near Amherst, Nova Scotia, form one of the world's premiere Carboniferous coal-bearing exposures. A 145 m section was measured in the vicinity of Bell's Brook. The section is classified into three ... -
URANIUM, RADIUM, AND RADON IN STREAMS, DOMESTIC WELL WATERS, AND SOILS: A GIS ANALYSIS OF GEOLOGICAL, GEOCHEMICAL, AND GEOPHYSICAL RELATIONSHIPS
(1999-04-15)Elevated levels of 238Uranium (U) and its daughter products 226Radium (Ra) and 222Radon (Rn) in groundwater, surface water, and soils have the potential of posing health risks. In particular, high levels of radioactive ... -
Ancient Submarine Canyons. and Fans of the Carson Basin, Grand Banks, Offshore Newfoundland, Canada
(1999-04-15)The Carson Basin lies beneath the Grand Banks, offshore Newfoundland, and is composed of several depocenters, the deepest of which holds over 7 km of Mesozoic and Cenozoic strata. To date only four exploration wells have ... -
EXPERIMENTAL EVALUATION OF SUBAQUEOUS DISPOSAL OF ACID GENERATING SULPHIDE MINERALS IN THE MEGUMA SUPERGROUP, SOUTHERN NOV A SCOTIA
(1999-04-15)Development and construction projects that require the disturbance and excavation of sulphide rich bedrock in Halifax and southern Nova Scotia produce large quantities of waste rock material. This material poses a high ... -
RECONSTRUCTION OF POLLUTION HISTORY AT MILL COVE, BEDFORD BASIN USING BENTHIC FORAMINIFERA
(1999-04-15)The comparison of data from two cores collected in Bedford Basin, adjacent to the Mill Cove Sewage Treatment Plant, in August 1998, to data from 1968, 1993 and 1996, allows the impact of pollution to be determined. Benthic ... -
Cambrian Multichambered Foraminifera from the Halifax and Goldenville Groups of the Meguma Supergroup, Nova Scotia
(1998-04-15)Foraminifera in the Cambrian are rare; only ten genera have been recorded and these were all simple tubular and branching unilocular forms found in West Africa. The discovery of an organic lens within the Goldenville ... -
