Unit Name: Kennedy Channel Formation
Unit Type: Lithostratigraphic
Rank: Formation
Status: Formal
Usage: Currently in use
Age Interval: Proterozoic (2500 - 542 ma)
Province/Territory: Nunavut
Originator: Kerr, 1967b.
Type Locality:
West shore of Kennedy Channel, 29 km S 50 deg E (true) of the head of Ella Bay, Ellesmere Island.
Distribution:
At the type section, where its lower limit is not exposed, the formation has a thickness of 1,113 m, while at Scoresby Bay, only 107 m of fine-grained quartzose sandstone is exposed. The formation is apparently confined to the Franklinian Miogeosyncline of central eastern Ellesmere Island.
Lithology:
A slightly metamorphosed (phyllitic), heterogeneous assemblage of mainly dark grey, dark weathering limy phyllite, dolomite, thin-bedded, fine-grained limestone, and rusty weathering laminated quartzose sandstone. The phyllites and limestones exhibit a common white bloom on weathering surfaces in the type area.
Relationship:
The lower contact of the Kennedy Channel Formation has not been ob-served and described, as it is the oldest known sedimentary unit in the Franklinian Miogeosyncline. The formation is overlain with regional disconformity and local angular unconformity by the younger Proterozoic Ella Bay Formation.
