Available in PDF, EPUB and Kindle. Book excerpt: "Two hundred and eight potassium-argon age determinations carried out on Canadian rocks and minerals are reported. Each age determination is accompanied by a description of the rock and mineral concentrate used: brief interpretative comments regarding the geological significance of each age are also provided where possible. The experimental procedures employed are described in brief outline and the constants used in the calculation of ages are listed. Two geological time-scales are reproduced in tabular form for ready reference and an index of all Geological Survey of Canada K-Ar age determinations published in this format has been prepared using NTS quadrangles as the primary reference." --

Download or read book Geological and Tectonic Framework of Eastern Canada as Interpreted from Potential Field Imagery written by J. M. Woodside and published by Geological Survey of Canada. This book was released on 1989 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent compilation of all gravity and magnetic anomaly data for offshore and eastern Canada provides an unprecedented perspective on the geological framework of the region. Classification of the region by similarities in the patterns and trends of gravity and magnetic data observed at a scale of 1:5,000,000 indicates geological affinities within structural provinces and tectonic relationships between geological domains. This report examines the correlation between the potential field data and regional geology, and provides a key to the published results and current research on regional structure as interpreted using the available geophysical and geological information.
