It is an over 1000 m thick succession of siliciclastic deposits that were deposited during the Fortunian stage including the Proterozoic/Cambrian-boundary. Sequence stratigraphy shown ehre: Starts in intertidal zone, then as cambrian progresses becomes deeper water (outer shelf) (general trend). The Chapel Island Formation lies on top of the Rencontre Formation and below the Random Formation.
