Lithology description: This high diversity assemblage occurs in interbedded calcareous shales and thin calcarenitic limestones.
Environment:offshore Tectonic setting:foreland basin
Glacial or sequence phase:highstand systems tract
Geology comments: relatively shallow depositional environment, affected by frequent storm action (average storm wave base) but slightly below normal wave base. An outer BA 3 (offshore shoal) assignment is indicated.
