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 ...
Geochemistry and Petrogenesis of Late Cretaceous Bentonites from the Kanguk Formation, Axel Heiberg and Ellesmere Islands, Canadian High Arctic
(1994-03-15)
Petrographic and geochemical analyses of bulk bentonites, volcanic minerals, and unaltered glass inclusions in quartz phenocrysts reveal the composition and tectonic setting of Late Cretaceous explosive volcanism in the ...
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, ...
