...Charles F. Stehman Abstract Study of the sediments found in northern Placentia Bay, Newfoundland, using MS-26-B echosounder profiles and 87 grab samples, reveals that sediments in that area are derived principally from glacial sources. Sediment facies distribution patterns are contrastingly...

...D. C. Ford Abstract South Nahanni National Park transects the southern Mackenzie Mountains from a position close to the continental divide to their eastern limit. In the context of glaciation it displays three distinct zones: I, in the west, a cordilleran glacial zone with evidence of two or more...

...Hugh H. Mills Abstract Denudation rates on Mount Rainier, Washington, were determined by estimating dissection of the original landform, volumes of glacial and lahar deposits, present sediment loads of meltwater streams, reservoir sedimentation rates, and super-glacial debris loads. Rates...

...B. D. Stone Abstract Slumped glacial delta sands and silts exhibit flexural slip folds and low-angle thrust faults where the beds remained coherent during slump deformation. Alternating cross-cutting relationships between f (sub l ) and f (sub r ) fold axial planes indicate that these fold groups...

... Glaciation. This change apparently occurred before 28 800 y BP, substantially earlier than glacial occupation of the southern Interior Plateau of British Columbia. Thus, several thousand years may have intervened between the alpine and ice-sheet phases of the Fraser Glaciation. Le Sable de Quadra est...

... latitudes with glacial periods. Initial testing of this model is now extended using nine Eltanin piston cores from the southeast Indian Ocean. Frequency variation in the Antarctic radiolarian Antarctissa strelkovi is used as a paleotemperature index, and the ice-rafted debris is measured for the 62- to 250...

...N. Ahmad Abstract Glacial origin of Talchir deposits of India has long been accepted but along with this all the tillites have also been regarded as the lower most Talchir bed. The author has found that in Sone valley this is not true and the tillites are Upper Talchir in age. Beds older than...

...John J. Clague Abstract The southern Rocky Mountain Trench was a major outlet valley of the Cordilleran Ice Sheet. Quaternary sediments underlying the floor of the trench in southeastern British Columbia consist mainly of glacial, glaciofluvial, and glaciolacustrine materials deposited during...

...Sigmund Hammer; C. Patrick Ervin Abstract Roseau Lake in northwestern Minnesota occupies a conspicuous, circular depression in a level plain of glacial drift. A detailed gravity survey of the lake was made to determine if the Precambrian bed rock under the thin cover of glacial drift exhibited...

...Peter A. Peach; Lesley Anne Perrie Abstract Climatic variations lasting a few days can produce variations in the coarseness of the grain size within the summer phase of glacial varve couplets. Studies of size distribution made with a Quantimet 720 make it possible to resolve these variations...

...Darrel G. F. Long Abstract Conglomeratic rocks of the Chibougamau Formation are interpreted as the products of deposition in a glacial and paraglacial environment, in an area of undulating topography at the margin of an extensive Aphebian ice sheet. Mixtiles and graded laminites with dropstones...

... stratigraphic and tectonic setting strongly favor a glacial origin for the diamictite; this corroborates previously published views. We postulate a glaciomarine model, however, to explain the Talchir sedimentation in the study area. The ice sheets may have advanced into central India from the south several...

... and glacial erosion during the Quaternary.The seismic refraction measurements indicate that the Tertiary sediments on the west coast of Norway extend closer to the coast than previously suggested. Un levé séismique par réflexion et réfraction a été fait dans le chenal de Norvège entre les latitudes 59.5...
