• 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 south coast the Ferrum Member is at least 32 m thick. It is characterized by marked lithologic variability with thin-bedded micrite with calcareous mudstone partings, thin calcarenites, hardgrounds, and intraformational conglomerates."
