Northern Appalachian Transect: Southeastern Quebec, Canada Through Western Maine, U.S.A.; Quebec City, Canada to Portland, Maine, July 20-26, 1989

Published by the American Geophysical Union as part of the Field Trip Guidebooks Series.
This excursion crosses the entire exposed width of the northern Appalachian orogen, from Quebec City, Canada, south to Portland, Maine, a distance of 230 mi (370 km). Because of the great distance and the great complexity of the geology, we decided to focus on specific areas of outstanding interest, rather than attempt to show all that can be seen in the time available. Emphasized throughout are the primary lithologic features that characterize the principal lithotectonic belts shown on Figure 1, which also shows the outlines of the detailed maps for six of the seven days of the excursion. No guide article and detailed map has been prepared for day 3, which is open for several options in Quebec Province near the Maine border.
