Marginal Marine Foraminifera and Thecamoebians in the Upper Cretaceous to Eocene Deposits of the South-Central Pyrenees, Spain
(1995-04-15)
The Upper Cretaceous to Eocene marginal marine sediments, in the northeastern Pyrenees of Spain, is a classic area in which to study sequence stratigraphy. Sequence stratigraphy requires strong sea-level control. The ...
Structure of Bedrock Offshore From Point Aconi, Cape Breton Island, Nova Scotia
(1995-04-15)
The Prince Colliery is a major offshore coal mine operated by the Cape Breton Development Corporation (DEVCO) in the Hub coal seam of the Sydney Mines Formation (Upper Carboniferous). This thesis presents the results of a ...
40Ar/39Ar Thermochronology Across a Transect of the Eastern Grenville Front Tectonic Zone and the Western Britt Domain of the Grenville Province, Georgian Bay
(1993-03-15)
40Ar/39Ar thermochronology of hornblendes from granitic gneiss and amphibolites in the Central Gneiss Belt (CGB) west of Key Harbour along northern Georgian Bay yields ages ranging from 1016 - 995 Ma. Muscovites from the ...
The Geochemistry and Geochronology of the Shelburne Dyke of Nova Scotia and the Messejana Dyke of Spain
(1994-03-15)
This paper is a geochemical and geochronological study of two rift-related Mesozoic basaltic dykes. The Shelburne Dyke of Nova Scotia and the Messejana Dyke of Spain are extensive vertical sheets of intrusive rock that are ...
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 ...
Structure of the Dunamagon Granite, Baie Verte Peninsula, Newfoundland
(1994-03-15)
New Structural data from field observations and microstructural analysis are the basis of description of structures in the Dunamagon Granite, for the purpose of determining whether it has an intrusive, or tectonic, contact ...
Contact Relations Between The New Ross Leucomonzogranite and the Falls Lake Mafic Porphyry: Evidence for Magma Interactions in the South Mountain Batholith
(1994-03-15)
The South Mountain Batholith is a peraluminous composite batholith that intruded over a short interval of time. The batholith consists of 260 intrusive bodies, thus the possibility of magma-magma interactions is high. The ...
Sediment Consolidation and Permeability at the Central Oregon Margin, Ocean Drilling Program Sites 891 and 892
(1994-03-15)
Sediment hydraulic conductivity is a critical and highly variable control on the consolidation of accretionary prism materials. The consolidation state and pore pressure conditions within an accretionary prism ultimately ...
Physical Volcanology, Petrology, and Petrogenesis of the Cretaceous Isachsen Formation Volcanics, Western Axel Heiberg Island, N.W.T.Formation Volcanics, Western Axel Heiberg Island, N.W.T.
(1994-03-15)
New data from Bjarnasson Island and Bals Fiord on western Axel Heiberg Island provide insight into the physical volcanology, petrology, and petrogenesis of Cretaceous Isachsen Formation magmatism. The Bjarnasson Island ...
GEOMETRY AND DEPOSITIONAL SETTING OF THE LATE CARBONIFEROUS MULLINS COAL IN THE SOUTH BAR FORMATION, SYDNEY BASIN, NOVA SCOTIA
(1994-03-15)
The three-dimensional geometry of the Mullins Coal (Westphalian C) provides information about its origin and potential for commercial exploitation. Controls for peat accumulation are allogenic in contrast to a previous ...
