The study area covers most of the Northern Peninsula of Newfoundland, including the north end of the Long Range Mountains together with fringing uplands and lowlands. This report presents the final results of surficial mapping of this area of Newfoundland at 1:250,000 scale. The work was conducted to map, describe, and explain the unconsolidated deposits and landforms to provide areal knowledge of geology and terrain as background information relative to land-use planning, mineral exploration, location of granular deposits, community water supply problems, forestry, urban and industrial development, and various aspects of engineering construction, and to determine the Quaternary history.
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 group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. The last deglaciation is also shown in 500 year time-steps. The digital maps in this volume cover the USA and Canada and include Greenland and Hawaii. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.Also available:Part I: Europe, ISBN 0-444-51462-7Part III: South America, Asia, Africa, Australia, Antarctica, ISBN 0-444-51593-3
The study was prompted by a need for data on terrain conditions, soil materials, and glacial transport, which was required for mineral exploration, for the planning of a hydroelectric transmission corridor, for bedrock mapping, for forest inventory, and for land capability studies. A secondary reason for beginning a program of surficial mapping in this part of Newfoundland was the paucity of Quaternary geological information in a key area about which early reports debated the extent of glaciation, and where airphoto reconnaissance revealed significant new glacial and marine formations.
Newfoundland lies at the intersection of arctic and more temperate regions and, commensurate with this geography, populations of two Amerindian and two Paleoeskimo cultural traditions occupied Port au Choix, in northern Newfoundland, Canada, for centuries and millennia. Over the past two decades The Port au Choix Archaeology Project has sought a comparative understanding of how these different cultures, each with their particular origin and historical trajectory, adapted to the changing physical and social environments, impacted their physical surroundings, and created cultural landscapes. This volume brings together the research of Renouf, her colleagues and her students who together employ multiple perspectives and methods to provide a detailed reconstruction and understanding of the long-term history of Port au Choix. Although geographically focussed on a northern coastal area, this volume has wider implications for understanding archaeological landscapes, human-environment interactions and hunter-gatherer societies.
This synthesis of the Quaternary geology of Canada and Greenland covers the regional Quaternary geology of Canada, applied Quaternary geology in Canada (including its influence on man's environment), the Quaternary geology of the ice-free areas of Greenland, and the dynamic and climatic history of the Greenland ice-sheet.
This report describes and explains the unconsolidated surface materials and landforms of Cape Breton Island, tracing the history of geological processes that shaped the area during the late Cenozoic time and emphasizing the previous interglacial period and the last glacial period. Initial field work was conducted in the summers of 1970 and 1971. Documentation of the surficial geological map units was by ground observation. Most of the coast was studied on foot, with the remainder by boat. Additional incidental observations, local stratigraphic studies, and traverse of new highland forestry access roads were made on an opportunity basis in 1974, 1976, 1982, 1993, and 1994.
New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continental slope, rise and deep-sea basins beyond. The distribution and geometry of these submarine landforms provide key information on past ice-sheet extent and the direction and nature of ice flow and dynamics. The papers discuss individual seafloor landforms, landform assemblages and entire landsystems from relatively mild to extreme glacimarine climatic settings and on timescales from the modern margins of tidewater glaciers, through Quaternary examples to ancient glaciations in the Late Ordovician.
