Glacial marine sediments in the precambrian Gowganda formation at Whitefish Falls, Ontario (Canada) Glacial marine sediments in the precambrian Gowganda formation at Whitefish Falls, Ontario (Canada)
Study of a well-exposed section of the Gowganda Formation at Whitefish Falls, Ontario, suggests criteria for the recognition of glacial marine sediments. Thickness of hundreds of feet, lateral continuity, faint internal stratification, sorted lenses of sandstone and conglomerate, and dropstones characterize much of the tillite. Thickness of hundreds of feet, lateral continuity, and...

Glacial sedimentology of the Precambrian Gowganda Formation, Ontario, Canada Glacial sedimentology of the Precambrian Gowganda Formation, Ontario, Canada
The Gowganda Formation is part of the thick Huronián sequence of Precambrian sedimentary rocks that crop out in central Ontario from Lake Superior to Quebec. Although it has long been considered to be glacial, recent work on submarine slump and turbidite deposits has reopened the question of its origin. This study was made to determine its origin and paleogeography.Till-like...

Sediment transport in a Precambrian ice age: The Huronian Gowganda Formation Sediment transport in a Precambrian ice age: The Huronian Gowganda Formation
The Gowganda Formation of Ontario consists of conglomerates, quartzites, and argillites deposited in a glacial environment. The distribution of varved argillites and silty limestones suggests continental and marine facies, respectively. Pebble and ripple-drift orientations, distribution of limestones, striated pavements, distribution of the underlying Bruce Group, and Huronian quartzite...
