• Member description taken from 2007 Long. Tempestite frequency curves: a key to Late Ordovician and Early Silurian subsidence, sea-level change, and orbital forcing in the Anticosti foreland basin, Quebec, Canada. Can. J. Earth Sci. Vol. 44, 413-431. "Along the northeast coast of Anticosti Island the Gun River Formation includes 85 to 90 m of grey to pale yellow weathering strata, which have been divided into four informal members (Lachute, Innommée, Sandtop, and Macgilvray) that can be traced with some confidence into the type section on the southwest coast (Long and Copper 1994)."
