Abstract
SUMMARY: Devonian limestone turbidites from North Cornwall, composed mainly of crinoidal debris, are considered to have been derived from an oceanic rise or schwelle. Large‐scale cross‐bedding (representing division C) occurs in some limestone bands. The turbidites lack a pelitic division and there is usually a sharp contact with the shales above. Typical flutes are rare but broad grooves and channels are present on the soles.Keywords
