Book Description
Presents geochronological age determinations of zircons from eight plutons in the Grenville Province, Ontario (Oso and Mountain Grove plutons in the Sharbot Lake domain; Silver Lake & Bennett Bay plutons and Fall River mangeritic augen gneiss associated with the Maberly shear zone; North Crosby & Pike Lake plutons in the north-west sheared part of the Frontenac terrane; and the Beales Mills pluton in the interior of the Frontenac terrane). The results are used to propose a re-interpretation of the tectonics of the Frontenac suite and the origin of the magmas responsible.

Book Description
This volume is made up of papers presented at a colloquium of the Geology Devision of Section III of the Royal Society of Canada at the annual meeting in Quebec, June 1963. The papers fall into two groups: in one group the validity and shortcomings of the methods of establishing the geographical time-table are discussed; and, in the other, applications of the methods to areas across Canada, and from Precambrian to recent, are described. The geological time-table has been built up from the record of the rocks and is based on the law of superposition, a fact that is pointed out in the first paper of this volume. The chronological value of fossils, palaeomagnetism as a means of dating geological events, the limitations of radiometric dating, and other pertinent matters are here dealth with by a group of well-known authorities. These scientific disquisitions will be of great importance to geologists everywhere. This work should be of special interest to those engaged in research on the history of the earth, particularly in relation to the nature, the causes, and the time of an event. It will also serve as a valuable reference to practising geologists in government or industry, to university departments of geology, and to geological consultants.

Book Description
This study examines aspects of the geological evolution of the Sharbot Lake domain and compares it with that of neighbouring domains & terranes in the Central metasedimentary belt, Grenville Province, Ontario. The study reports uranium-lead zircon & titanite geochronological ages for a granodiorite phase of the Pakenham intrusion from the northern part of the Sharbot Lake domain. The new data expand the known range of magmatism in this part of the belt, elucidate the early tectonic evolution of the domain, and constrain the timing of overprinting metamorphism. Possible links between the Pakenham structure and the Wolf Grove structure to the south-east are also discussed.

Book Description
This volume focuses on the Canadian Appalachian region. The chapter on the East Greenland Caledonides stands alone and there is no attempt to integrate the geological accounts of the two far removed regions. Rocks of the Canadian Appalachian region are described under four broad temporal divisions: lower Paleozoic and older, middle Paleozoic, upper Paleozoic, and Mesozoic. The rocks of these temporal divisions define geographic zones, belts, basins, and graben, respectively. The area is of special interest because so many modern concepts of mountain building are based on Appalachian rocks & structures.
