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, ...
Holocene Relative Sea-Level Change in Nova Scotia
(1993-03-15)
Core samples collected around Atlantic Canada, specifically from the West Head salt marsh, Chezzetcook Inlet, enable temporal and spatial examination of benthic foraminiferal assemblages. Benthic foraminiferal zonations, ...
Comparison of Siliceous Volcanics from the Clarno and John Day Formations, Oregon
(1993-03-15)
The Tertiary Clarno and John Day Formations occur in the Blue Mountains Region of north-eastern Oregon. The two formations are easily distinguishable overall, because the Clarno consists primarily of andesitic to dacitic ...
Cooling and Uplift Pattern of the Liberty Hill Pluton, South Carolina, USA
(1988-04-15)
The Liberty Hill pluton is one of a series of post-metamorphic plutons emplaced in the central and eastern Piedmont province of the Appalachians in the late Paleozoic. An investigation of the post-magmatic cooling and ...
Geological Investigation of a Mineralized Granitic Cupola, Kempt Snare Lake, Yarmouth County, Nova Scotia
(1988-04-15)
At Kempt Snare Lake, a leucogranite and leucomonzogranite cupola, with a composition similar to the Davis Lake Pluton, intrudes the metawackes of the Goldenville Group. 40Ar/39Ar dating constrains the age of intrusion to ...
