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.
This book is the second of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared.The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work g...
Shale gas is to New Brunswick today what the Free Trade Agreement with the United States was to Canada a quarter century ago: a deeply controversial, highly polarizing issue over which tempers quickly flare up. As was the case with the free trade debate, the public discourse on shale gas has degenerated into a war of words, with most citizens left in the middle with very little information they can trust to secure a better understanding of what is at stake. This study aims to fill part of the wide information gap on shale gas in New Brunswick. While substantial knowledge has been built in recent years on the impact—both positive and negative—of shale gas on communities where it is active...
