First published in 1985, Quaternary Environments represents the culmination of Quaternary research in the region of Baffin Island, Baffin Bay and West Greenland over a period of twenty years and it will serve as a timely and complementary balance to the paleo- oceanographic studies in the NE North Atlantic. The region of Baffin Island, Baffin Bay and West Greenland is probably the best place in the world to examine the interactions between ice, land and oceans on timescales of a few hundred to many thousands of years. Two introductory chapters outline the history of research and the physical background. In Part II the evidence for glacial erosion and deposition over the eastern Canadian Arctic is examined and the history of the Baffin Island continental shelf is described. Part III deals with the paleo- oceanography of Baffin Bay and the Labrador Sea through an examination of deep-sea cores dated by several different methods. In Part IV there is a comprehensive account of the stratigraphy of Baffin Island, Bylot Island, and West Greenland, from the Pliocene to the late Wisconsin. Part V examines the climatic effects of the past 10,000 years, considering evidence from pollen analysis, glacier fluctuations, changes of sea level and the response of early (Eskimo) man. This important volume will interest all quaternary scientists, especially those in glaciology, glacial geology, marine geology, and geomorphology.

Developments in Geotectonics, 9: Recent Crustal Movements covers the papers presented at the Fifth International Symposium on Recent Crustal Movements, held in Zurich, Switzerland on August 26-31, 1974. The book focuses on geodetic investigations, geological-geomorphological investigations, geophysical investigations, in-situ stress measurements/crustal stresses, seismotectonics/active faults, and plate tectonics/continental drift. The book first takes a look at tectonic-plate motions from lunar ranging and long baseline interferometry for centimeter accuracy geodetic measurements. Discussions focus on proposed transportable lunar laser ranging station; expected plate-motion measurements from present lunar-ranging stations; and pacific plate motion experiment. The text then ponders on precision electromagnetic distance-measuring instrument for determining secular strain and fault movement and deep in-situ stress measurements by hydrofracturing. The publication ponders on geotectonic relevance of rock-stress determinations, thermal runaway in the mantle and neotectonics, and data on plate tectonics of Alaska. The text also elaborates on geodetic surveys for monitoring crustal movements in the United States and determining earthquake recurrence intervals from deformational structures in young lacustrine sediments. The manuscript is a vital source of data for readers interested in crustal movements.

Developments in Geotectonics, 15: Crustal Properties across Passive Margins covers the papers presented at the symposium ""Crustal Properties across Passive Margins"", held at Dalhousie University in Halifax, Nova Scotia on June 19-23, 1978. The book focuses on theoretical modelling of the rheological properties in the upper mantle beneath oceans and continents and stratigraphic studies of the sedimentary basins. The selection first offers information on seismic refraction study of the continental edge off the Eastern United States and gravity field of the U.S. Atlantic continental margin. Topics include crustal sections, inner and outer quiet zones, alternative models and complications, gravity models, free-air anomaly map, and the ocean-continent transition zone. The text then takes a look at the geologic history of the passive margin off New England and the Canadian Maritime Provinces and geophysical observations bearing upon the origin of the Newfoundland Ridge. The manuscript elaborates on the age and origin of the deepest correlative structures recognized off Canada and Europe and geophysical transects of the Labrador Sea. Discussions focus on magnetics and gravity, stratigraphic control, consequences regarding subduction or rifting, and deep structures of the Grand Banks of Newfoundland. The selection is a dependable reference for readers interested in crustal properties across passive margins.
