Identification of the Carrier of Magnetization in a Basalt Core from Bermuda
(1987-04-15)
Peckenham (1981) attempted to use the magnetic properties of a basalt core from Bermuda to help him define the stratigraphy of basalt flows present in the core. The results of his investigation were not helpful. Magnetic ...
Regional Mapping and Petrographic Study of a Silurian Gneissic Complex, Belle Cote Road, Cape Breton, Nova Scotia
(1987-04-15)
The Leblanc Lake area is located in the central Cape Breton
Highlands south of the Cheticamp River. The main study area is
situated along Belle Cote Road, one of the numerous logging roads
in the region. Mapping at ...
A Geochemical Study of the Carboniferous Audhild Volcanics, Northwestern Ellesmere Island, Arctic Canada: Initial Volcanism in the Sverdrup Basin
(1989-04-15)
Spilitized basalt flows constitute the largest portion of the Late Carboniferous Audhild Formation exposed on Kleybolte Peninsula, northwestern Ellesmere island. The flows were erupted subaerially and are commonly separated ...
The Petrology and Geochemistry of the Port Mouton Migmatites
(1987-04-15)
This study is centered on the migmatites found along certain portions of the contact between the Port Mouton pluton of Shelburne and Queens counties, Nova Scotia, and the local host lithology. The field relations, petrology ...
Palynology and Stratigraphy of an Upper Cretaceous Sedimentary-Volcanic Sequence, Emma Fiord, Northwest Ellesmere Island, N.W.T, Canada.
(1989-04-15)
Terrestrial sedimentary units (lignite and siliclastics) are interbedded with bimodal volcanic units (alkali basalts, silicic volcanics and pyroclastics) on an unnamed peninsula between Audhild Bay and Emma Fiord (81o30'N, ...
40Ar/39Ar Thermochronology of the Britt Domain Grenville Province - Georgian Bay, Ontario
(1989-04-15)
The 40Ar/39Ar thermochronology of a transect of the Britt domain, Central Gneiss Belt, Grenville Province has been examined in this study. In total, twelve argon gas analyses were obtained. These came from five locations ...
Sedimentation of the Barrow Group, Exmouth Plateau, Northwestern Australia
(1989-04-15)
The Exmouth Plateau is a major promontory of the north western Australian continental shelf and ranges from longitude 111oE to 117oE throughout southern latitudes 16o to 21o. This plateau has an aerial extent of approximately ...
Hydrothermal Alteration, Gold Distribution and Geochronology of Epithermal Gold Mineralization in the Copiapo Volcanic Complex, Chile
(1986-04-15)
This thesis is a pilot project of an ongoing investigation into the gold metallogenesis in the Copiapo volcanic complex, Chile. The study is aimed at understanding the pattern of hydrothermal alteration and its relation ...
A Study of a Late Devonian-Carboniferous, Porphyritic Microgranite-Hosted, Hydrothermal Breccia Pipe in the Mount Pleasant Caldera Complex, New Brunswick, Canada
(1987-04-15)
The South Oromocto Lake (SOL) breccia zone is located approximately 5.3km NE of Mount Pleasant in the Mount Pleasant caldera complex, south-western New Brunswick, Canada. Late stage hydrothermal activity during cooling of ...
AR-40/AR-39 AGE STUDIES OF MAFIC VOLCANICS FROM THE SVERDRUP BASIN, ARCTIC CANADA
(1987-04-15)
Cretaceous extrusive volcanism in the Sverdrup Basin is widespread and appears to have occurred in four major episodes (Valanginian, late Barremian, late Albian, and late Cenomanian/early Turonian). In addition to these ...
