A Lower Carboniferous Sedimentary-Volcanic Succession, North Baddeck River, Nova Scotia
(1982-03-15)A comprehensive study was made on a roughly 60 metre thick succession of sedimentary and volcanic rocks on the North Baddeck River, central Cape Breton Island, Nova Scotia. The sequence comprises thinly-laminated grey ... -
DEPOSITIONAL ENVIRONMENT OF THE LOWER PALEOZOIC SEDIMENTS ON THE GRAND BANKS OF NEWFOUNDLAND
(1982-03-15)Lower Paleozoic platformal sediments on the Avalon Peninsula continue offshore in the area between the Avalon Peninsula and the Virgin Rocks. Dating of ten drilled cores from the offshore area and continuous seismic profiles ... -
A Study of Sulfide Mineralization in the Meguma Group Sediments Gold Brook, Colchester County, Nova Scotia.
(1982-03-15)A preliminary study of representative drill core from the Gold Brook property (of Sulpetro Minerals Limited), Colchester County, Nova Scotia was undertaken, to describe the styles of strata-bound and vein-type mineralization ... -
Geology, Geochemistry, and Genesis of the Brazil Lake Pegmatites, Yarmouth County, Nova Scotia
(1982-03-15)The Brazil Lake pegmatites, located about 25 km northeast of Yarmouth, intrude amphibolites and orthoquartzites of the White Rock Formation on the eastern flank of the Yarmouth syncline. The pegmatites are of igneous origin ... -
Marine and Coastal Geology Between Hartlen Point and Jeddore Cape, Nova Scotia
(1982-03-15)Acoustic and sample data have been collected in a 600 km2 area of the innermost Scotian Shelf along the Eastern Shore just east of Halifax. In addition sediment distribution has been mapped and rates of coastal change ... -
Magnetic Properties of a Bermudian Pillowed Lava Flow
(1982-03-15)This study is concerned with the description and interpretation of the opaque mineralogy and paleomagnetic properties of a 3.0 m core interval which is comprised of a pillowed lava flow and basal intrusive sheet taken from ... -
Whole Rock Analysis using the Electron Microprobe
(1981-03-15)Rock powders ranging in composition from a peridotite to a granite were fused on molybdenum and tantalum strips in a vacuum and a nitrogen atmosphere. A low voltage high amperage source was used to melt the rock powders. ... -
The White Rock Formation Metavolcanics at Cape St. Mary, Nova Scotia: Petrography, Geochemistry, and Geologic Affinities.
(1981-03-15)A 156 meter thick section of the Silurian White Rock Formation occurs at Cape St. Mary, southern Nova Scotia in the core of a southwest plunging syncline. It includes four metabasite units identified as basaltic flows, and ... -
Depositional Analysis of the Upper Meguma (Halifax Formation) at Ovens Park, Lunenburg County, Nova Scotia
(1981-03-15)Two sections of the Halifax Formation, Meguma Group (Lower Paleozoic) at Ovens Park, Nova Scotia, were examined for sedimentary structures, grain size and facies associations. Interpretation of the depositional processes ... -
Depositional Environments and Diagenesis of a Section of the Herbert River Limestone Member, Windsor Group, Upper Pleasant Valley, Nova Scotia
(1980-03-15)A stratigraphic section of the Herbert River Limestone Member, Windsor Group, exposed on Pleasant Brook, Upper Pleasant Valley, N.S., consists of ten carbonate lithologies. From base to top of section (with their respective ... -
Development of the Active Layer, Tuktoyaktuk Peninsula and Richard’s Island area, Western Arctic, Canada (Postprint)
(1982-03-15)During the 1979 field season, a large number of measurements of active layer thickness were obtained at a number of locations in the Tuktoyaktuk Peninsula/Richard’s Island area, N.W.T., by probing the ground surface with ... -
A Detailed Study of a Submerged Pingo-Like-Feature in the Canadian Beaufort Sea, Arctic, Canada (Postprint)
(1982-03-15)There is controversy as to the origin of the dome shaped hills (pingo-like-features (PLFs)) found on the Canadian Beaufort Sea continental shelf and slope. A detailed study of a PLF was undertaken to define its characteristics ... -
SCALE MODEL EXPERIMENTS WITH THE HORIZONTAL LOOP ELECTROMAGNETIC TECHNIQUE OF GEOPHYSICAL PROSPECTING Postprint
(1982-03-15)This study deals with the construction and application of a scale model horizontal loop electromagnetic system whose function is to quantitatively measure the in-phase portion of the vertical component of an anomalous ... -
Petrogenesis of the Goose Cove Copper Deposit, Northwestern Newfoundland.
(1983-03-15)The Goose Cove copper deposit lies within the Goose Cove Schist of the St. Anthony Complex, northwestern Newfoundland. The initial theory of ore emplacement was epigenetic replacement of the greenschist host rocks (Stephenson, ... -
A Petrologic Study of the Hydrothermal Alteration and Ore Mineral Deposition in Drill Core Samples from Agrokipia, Cyprus.
(1983-03-15)The effects of hydrothermal alteration and ore mineralization were studied in 34 basalt drill core samples from the Agrokipia Cretaceous seafloor hydrothermal system in Cyprus. Transmitted and reflected light microscope, ... -
A Study of the Silica-Undersaturated Alkaline Rocks of the Laacher Sea Area, East Eifel Volcanic Field, West Germany
(1983-03-15)The generation of alkaline rocks is a complex process. The East Eifel volcanic field in West Germany represents the most alkalic rocks in the alkaline province of Central Europe and France. The area of particular interest, ... -
