Abstract
The Nikanassin Formation of the Type Area, Near Cadomin, Alberta [Abstract]
Four sections of type late Jurassic Nikanassin Formation from the central foothills of Alberta are presented.
Mechanical analyses of seven samples are given on histograms and cumulative frequency curves. A depauperate foraminiferal assemblage is listed. Heavy mineral descriptions are given throughout a complete section and eighty-two thin sections are analyzed.
The Nakanassin Formation belongs to the upper part of the Oxfordian Stage

and subsequent Jurassic stages. The Nikanassin is partially marine and partially continental; deposition may have taken place in shallow embayments connected to the open sea by narrow chanel-ways. The Nikanassin was largely derived from pre-existing sediments.
