This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents preliminary results from field observations on the Lower Silurian La Vieille Formation in north-east New Brunswick regarding the extent of early hydrothermal dolomitization, a critical element for assessing hydrocarbon potential. Six stratigraphic sections of the Formation were carefully examined for facies architecture and evidence of hydrothermal alteration of limestone facies. Features of interest included early fractures, brecciation & dissolution associated with early fractures, large-scale collapse of sections, fracture-filling cements, and synsedimentary tectonic instability. The findings provide critical information pertinent to the hydrocarbon reservoir potential of these rocks.

Book excerpt: The purpose of this paper is to document results of pore size analyses of rocks from the Astarte River Formation, central Baffin Island, for use in interpreting ground electromagnetic surveys that have been conducted in the central Baffin region. Results are presented for pore size distribution analyses of four black graphitic shale samples subjected to mercury injection porosimetry measurements. These measurements are essential for the electrical mechanism analysis of these samples. Porosity values are compared to those typical of mudstone or crystalline rocks.

Book excerpt: This paper presents results from uranium-lead dating of plutonic, volcanic, & sedimentary rocks from the Southern Indian Lake to Granville Lake area of northern Manitoba. The samples analyzed were collected from a range of tectonostratigraphic settings and provide constraints on the age of volcanism & sedimentation in the Rusty Lake Belt, on the deposition of fluvial to littoral facies sediments in the Partridge Breast Belt, and on the emplacement of orthogneiss and plutonic rocks.

This book was released on 2004 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dolostone mounds over 200 metres thick and over four kilometres across developed in deep water during uppermost Arctic Bay Formation shale deposition in the north-west Milne Inlet Graben on northern Baffin Island. This paper describes the geometry of hitherto unrecognized mounds that have been identified from field work in five areas: the Saint Georges Society Cliffs near Arctic Bay; beneath the Nanisivik lead-zinc deposit; Red Rock valley; Magda Lake; and Bellevue Mountain. Their lithology, lateral facies relations, and internal composition are described and an interpretation of the origin & growth of the mounds is offered. Finally, implications of mound growth & distribution for the fault-related flow of mineralizing fluids and consequent base-metal deposition are discussed.

This book was released on 2004 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper addresses previous interpretations of the origin of planar laminae and breccia networks found in carbonate rocks of the Society Cliffs Formation, which hosts numerous base metal showings and the Nanisivik zinc-lead deposit on northern Baffin Island. Field observations concerning the sedimentology of the Society Cliffs basinal laminite and the types of breccia found in laminite are presented and a new interpretation of the origin of these rocks is offered. Implications of the findings for oceanic chemistry & base metal mineralization are briefly discussed.

This book was released on 2004 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Milne Inlet Graben on northern Baffin Island contains unmetamorphosed sedimentary & volcanic rocks. The middle part of the Graben includes the Society Cliffs Formation, which hosts numerous base metal showings and the Nanisivik lead-zinc deposit. Known mineralization in the Graben is predominantly limited to distinct lithofacies & stratigraphic levels of that formation. Understanding the formation's composition, origin, and lateral facies relations may be critical to determining constraints on mineralization. Existing stratigraphic nomenclature for the Formation, based on a type section in the north-west part of the Graben, does not adequately characterize the lateral variations in facies from the north-west to south-east and does not account for the Formation's evolution over time. This paper critically reviews previous research on the Formation, which has focussed on the south-east part of the Graben, and fills in the gaps in knowledge about the Formation's sedimentology & stratigraphy. It describes the distribution & lateral relations of the various lithofacies and interprets the characteristics of the basins in which they were originally deposited.

Book excerpt: This report details the results of geochronological measurements made on 19 samples from locations in & directly adjacent to the eastern Bella Coola map area of British Columbia. The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas. Analytical data, geological ages, and relevant observations for each dated sample are presented in chronological order. The age results provide broad constraints on pluton emplacement, volcanic eruption, and structural & metamorphic relationships in the study area, although these are discussed only in general terms.

Book excerpt: Dans le cadre de la partie 2 du projet sur les ressources énergétiques des Appalaches de l'Initiative géoscientifique ciblée, nous avons utilisé un étinceleur pour obtenir plus de 3000 km de profils sismiques monotrace à haute résolution dans l'estuaire du Saint-Laurent. Ces données, recueillies en 2003 et 2004 en vue de cartographier des séries sédimentaires à de faibles profondeurs, contiennent de nombreux artéfacts, par exemple des réflexions multiples de courte et de longue périodes. Afin de fournir dans la mesure du possible des profils sans artéfacts, nous avons établi un processus à 10 étapes qui a servi pour le traitement des 55 profils obtenus. Ce processus comporte un algorithme de déconvolution trace par trace qui permet de comprimer la signature de la source. Les profils traités fournissent une image sismique améliorée qui permet de sélectionner avec précision les réflecteurs stratigraphiques clés.
