Lithology description: 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 32 to 34 m thick Cybèle Member is characterized by thin- to medium-bedded, predominantly barren micrites with minor thin calcarenites. Bioturbation and hardground surfaces are common. Laminated calcareous mudstones may be present locally but are poorly exposed." | |||
