Abstract

The upper boundary of the Middle Devonian Malbaie Formation is an angular unconformity below the Carboniferous Cannes de Roche Formation; although previously unrecognised, it is well exposed along the coast west of Pte-St-Pierre, Quebec. The lower boundary defined in 1935 on the shore northwest of Pte-St-Pierre is thought to be incorrect, representing stata about 500 m above the base of the formation. Logan's proposal that the boundary at this location is a fault contact with the Lower Devonian Battery Point Formation is accepted as a better interpretation.
