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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
