The Nature of Magmatism in the Appalachian Orogen
The thermal evolution of mountain belts is recorded inthe distribution, origin and ages of magnatism. In this volume, petrologic, isotopic and geochemical evidence is presented to highlight the contribution of igneous rocks to the evolution of the Appalachian Orogen in both Canada and the United States. These papers emphasize the use of modern geochemical and petrologic data to discriminate the sources yielding magmas, and thus the nature of the crust and mantle.

Lowestoft in olden times
This work presents a well-written and detailed history of Lowestoft, a town in the English county of Suffolk. Lowestoft is the most easterly UK settlement and the most famous city in the district. The author includes the history of old Yarmouth to explain the subject, as the rise of Lowestoft was associated with the fortunes of Yarmouth to a great extent. The author describes the place with vivid details and interests the readers with unknown facts. It is a must-read for all history enthusiasts. Contents include: Introduction Lowestoft in the 14th Century Lowestoft in Elizabeth's Time Lowestoft in the Times of Charles I and Charles II
Geology of the Appalachian—Caledonian Orogen in Canada and Greenland
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.

Betts Cove Ophiolite and Its Cover Rocks, Newfoundland
The Betts Cove area of the Baie Verte Peninsula, northern Newfoundland, is of interest for its mineral exploration history and for its ophiolitic complex formed through sea floor spreading. This study attempts to resolve some of the unresolved problems related to the area's stratigraphy, the magmatic affinity of its plutonic section, and the geologic controls on ore deposition. The report presents a revised stratigraphy for the area; a petrologic description of the rock units of the Betts Cove ophiolite, Snooks Arm Group, adjoining ophiolitic rocks, and post-Ordovician rocks; a history of structural deformation in the area; information on mineral chemistry, geochemistry, and petrogenesis; and tectonic models illustrating the evolution of the ophiolite and its cover rocks. The final section describes mineral deposits & occurrences in the area, including historic volcanogenic copper/sulphide mines, the currently producing Nugget Pond mine, and various gold occurrences.
