Carbonate Petrography and Stratigraphy of Holes 96, 100 and 106, Gays River, Nova Scotia: Implications for Depositional Environment
(1977-03-15)The lead-zinc deposit at Gays River, N. S. has been interpreted by previous studies as a Mississippi Valley type deposit hosted by an ecologic reef complex. Evidence now indicates that the host carbonate complex developed ... -
Foraminifera of the Minas Basin and their Distributions
(1977-08-31)One hundred and twenty-one samples of surficial sediments from all parts of the Minas Basin are analysed for foraminiferal content. Thirty-nine species are identified and described and maps of distribution are presented. This ... -
Partition of Uranium in Four Canadian Examples of Mississippi Valley Type Base Metal Deposits: Pine Point, N.W.T.; Polaris, N.W.T.; Newfoundland Zinc, Newfoundland; and Gay's River, Nova Scotia
(1977-12)Fission track analyses of minerals host rocks, and fission track mapping of uranium in samples from four Canadian Mississippi Valley type deposits, indicates that uranium concentrations in these samples are very minute ... -
A Study of some Trace Metals in Surface and Ground Waters at Bridgewater, Nova Scotia
(1978-03-15)Much controversy has arisen concerning the water quality in an area northwest of Bridgewater, Nova Scotia. To resolve the problem, water samples were taken and analyzed for trace metals, from the area which was also ... -
Stratigraphy and Depositional Environment of the Meaghers Grant Formation of the Musquodoboit Valley, Central Nova Scotia.
(1978-03-15)The Meaghers Grant Formation is a Lower Carboniferous siliclastic sequence in the Musquodoboit Valley of central Nova Scotia. It has been studied in outcrop and mainly in core. It lies wholly within the Lower Windsor Group ... -
Regional Geochemical Variations of Upper Cenozoic Volcanic Rocks in the Andes
(1978-03-15)Regional variations in the chemical composition of Miocene-to-Recent volcanic rocks from the Central Andes are investigated on the basis of 260 chemical analyses compiled from the literature in addition to 25 new analyses ... -
Subsidence of the Scotian Basin: A Theoretical Model
(1978-03-15)The development of a continental margin basin such as the Scotian Basin depends on various factors, exponential thermal contraction, sedimentary loading and the physical properties of the lithosphere underlying the ... -
Depositional Analysis of a Section of the Lower Meguma (Lower Paleozoic), Ship Harbour, Nova Scotia
(1978-03-15)A section of the lower Meguma (Lower Paleozoic) near Ship Harbour, Nova Scotia, was examined in detail in terms of bed thickness, sedimentary structures and grain size. Interpretation of depositional processes and ... -
An Application of Pleistocene Geology to Mineral Exploration in Southwestern Nova Scotia
(1978-03-15)An esker complex near Yarmouth, Nova Scotia has been investigated to determine the mode of origin of the eskers and to evaluate their usage in mineral exploration. Field work involved describing sections through eskers, ... -
Holocene History of Kings and Hartling Bays, Atlantic Coast of Nova Scotia
(1978-03-15)Kings and Hartling Bays are typical of many exposed inlets with bayhead beaches which are prevalent along the Atlantic Coast of Nova Scotia. The present morphology of these two bays is a result of Pleistocene glaciation ... -
Gravity and Magnetic Investigations of the Deep Cove Intrusive, Cape Breton County, Nova Scotia
(1978-03-15)Gravity and magnetic surveys were conducted on the Deep Cove quartz monzonite intrusive to ascertain its subsurface configuration and, in particular, the attitude of its west contact with the surrounding Fourchu volcanic ... -
Gravitational Interpretation and Modelling of the South Mountain Batholith. Southern Nova Scotia.
(1978-03-15)Much controversy surrounds the issue of the geometry of the South Mountain Batholith of southern Nova Scotia. Gravity data released by the Department of Energy, Mines and Resources within the last year has allowed a ... -
Geological, Mineralogical and Fluid-Inclusion Studies at the Dunbrack Lead-Silver Deposit, Musquodoboit Harbour, Halifax County, Nova Scotia
(1978-03-15)The Dunbrack deposit consists of a steeply dipping vein with argentiferous galena and other sulphides and sulphosalts in a gangue of predominantly quartz, hosted by altered adamellite granite. The vein appears to be ... -
Petrology and Geochemistry of Ignimbrites from the Bears Brook Volcanic Group, Arisaig, Antigonish County, Nova Scotia.
(1978-03-15)A chemical study of the ignimbrites of Arisaig, Nova Scotia, was undertaken to determine their geochemical character, any variations within flow units, and their relationship to associated volcanics. The ignimbrites are ... -
Structural Analysis of the George River Group at North Mountain, Cape Breton, Nova Scotia
(1978-03-15)Several different explanations of the structure of the George River rocks at North Mountain have been suggested in the past, none of which has proved to be very satisfactory. Milligan has proposed that the structure is ... -
Copper in the North Mountain Basalts, Nova Scotia
(1978-03-15)The North Mountain basalts are quartz-normative tholeiites stretching from Cape Split to Whipple, Nova Scotia. The lavas have been subjected to zeolite facies metamorphism. Native copper occurs in trace quantities associated ... -
