The purpose of this paper is to describe the detailed sedimentology and age data of Quaternary sediments in coastal exposures at Highlands, southwest Newfoundland. These exposures are critical to an ongoing debate on the extent and timing of a Late Wisconsinan readvance across the lowlands around St. George's by: During late Wisconsin time the major glacial advance in the western part of the region investigated reached its farthest extent south in at least three pulses: 21,, 19,, yrs ago. The oscillating retreats were interrupted by three documented . Lac La Jannaye, Quebec - Newfoundland / by I.M. Stevenson; Geology of Sunnyside map-area, Newfoundland, 1 N/ report and map / by W.D.

The absence of igneous and metamorphic clasts of Canadian Shield origin in the Saskatchewan gravels and sands (preglacial) valley fills in seven active gravel pits studied over a 5 yr period, coupled with 29 radiocarbon dates (21,, yr B.P.), suggest that Laurentide glaciation prior to the late Wisconsin did not reach the Edmonton by:

The Canadian Shield, also called the Laurentian Plateau, or Bouclier canadien (French), is a large area of exposed Precambrian igneous and high-grade metamorphic rocks (geological shield) that forms the ancient geological core of the North American continent (the North American Craton or Laurentia).Composed of igneous rock resulting from its long volcanic history, the area is covered by a Country: Canada, United States. covered northern New Jersey, and the most recent glaciation was during the late Wisconsinan substage, ab years ago.
