Unit Name: Blind Fiord Formation
Unit Type: Lithostratigraphic
Rank: Formation
Status: Formal
Usage: Currently in use
Age Interval: Early Triassic (251 - 245 ma)
Province/Territory: Nunavut
Originator: Tozer, 1963c.
Type Locality:
Northwest of Blind Fiord, Raanes Peninsula, Ellesmere Island.
Distribution:
Outcrops in a northeast-trending belt from Axel Heiberg Island to northwestern Ellesmere Island; probably present throughout the basinal part of the Sverdrup Basin. At the type locality, about 1,120 m thick but the thickness varies from 330 m at Bunde Fiord to 1,210 m at Buchanan Lake.
Lithology:
Mainly grey to green, partly micaceous siltstone; interbedded with grey shale in some areas.
Relationship:
The unit is a basinal equivalent of the Bjorne Formation. Blind Fiord silt-stones are paraconformably underlain by Permian cherty limestones at the type locality and are overlain with a sharp contact by the Blaa Mountain Formation.
