Opportunities and Challenges of Environmental Assessment under CEAA 2012
(2013-03)The objective of this study was to review how implementation of the Canadian Environmental Assessment Act 2012, as a part of the Canadian Federal Budget Bill (C-38), will affect environmental assessment, and ultimately ... -
The Origin and Emplacement of the Rock Units in Mule Creek, Northwestern British Columbia
(1983-04-15)In 1982 field work was carried out in northwestern British Columbia for Noranda Exploration Company, Ltd. Here a sequence of porphyritic and vesicular volcanic flows containing interbedded gypsum was discovered. Finely ... -
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 ... -
Origin of Foliation in the Barrington Passage Pluton
(1991-04-15)New studies provide insight into the processes producing the penetrative foliation observed in the Barrington Passage Pluton (BPP). Preferred alignment of primary minerals, imbrication of feldspars, preferred alignment of ... -
Paleo-sea ice conditions of the Amundsen Gulf, Canadian Arctic Archipelago: Implications from the foraminiferal record of the last 200 years
(2008-03)Four boxcores were collected as part of the Canadian Arctic Exchange Shelf Study (CASES) in the Amundsen Gulf at water depths of 59 m to 600 m. Data from these cores help to develop a record of changes in the oceanographic ... -
Paleoceanographic Reconstruction of the Inner Scotian Shelf During the Younger Dryas: A Benthic Foramineral Study
(1994-03-15)Examination of foraminifera from piston core 91-018-53P permits a paleoceanographic reconstruction of the Inner Scotian Shelf, with emphasis on the Younger Dryas cold period. A minimum in the total number of foraminifera ... -
Paleoceanographic Trends on the Northern Scotian Shelf
(1986-04-15)Paleoceanographic trends are recorded and reflected in the preservation of benthonic foraminiferal assemblages in ocean floor sediments. This study presents a succession of foraminiferal assemblages from an 8m core taken ... -
Paleoenvironment of Triassic Dinosaurs and Other Tetrapods at Carrs Brook, Nova Scotia.
(2000-04-15)A section of Triassic strata is exposed at Carrs Brook, on the northern margin of the Minas Subbasin, Colchester County, Nova Scotia. A detailed map of the Carrs Brook section was made using a plane table survey. The 200-300 ... -
Paleoenvironmental Analysis of Halifax Harbour: Sedimentology, Paleoclimatology, and Holocene Sea Level
(1994-03-15)Three cores (numbered 2,9,10) collected from Halifax Harbour using new submersible vibracoring equipment permits a reinterpretation of an acoustically distinct seismostratigraphic unit. This unit, never previously sampled, ... -
Paleosols of the Westphalian D Sydney Mines Formation, Sydney Basin, Cape Breton, Nova Scotia, Canada
(1992-04-15)Lacustrine-deltaic deposits in the Sydney Mines Formation contain paleosols. Three soil profiles (1 m, 1.2 m, and 0.9 m long) sampled over an 11.8 m interval of drill core taken ca. 200 m offshore Point Aconi, Cape Breton, ... -
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 ... -
Palynology and Stratigraphy of an Upper Cretaceous Sedimentary-Volcanic Sequence, Emma Fiord, Northwest Ellesmere Island, N.W.T, Canada.
(1989-04-15)Terrestrial sedimentary units (lignite and siliclastics) are interbedded with bimodal volcanic units (alkali basalts, silicic volcanics and pyroclastics) on an unnamed peninsula between Audhild Bay and Emma Fiord (81o30'N, ...
