Crossbedding measurements in the Val Brillant and Robitaille Formations suggest that the sand fraction of these beds was derived from two dispersal centers located west-northwest and north of the present Silurian outcrop belt. Some aspects of the textural and mineralogical maturity of the distribution of crossbedding azimuths and the presence of marine faunas in the sandstones indicate that the sands were deposited in a shallow marine environment of high energy level.
