•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. "The basal Fox Point member is dominated by thin-bedded sets of relatively clean unlaminated and laminated micrite, which are separated by thin sets of siliciclastic-rich carbonate mudstones. The lower part of the unit contains abundant discontinuous grainstone and carbonate sandstone units, with hummocky cross-stratification and local development of ball-and-pillow structures in proximity to stepped irregularities on the basal flooding surface (Fig. 3E; Long and Copper 1994). The Fox Point member thins from 22 m in the west to as little as 3.6 m in the east (Sami 1989)."
