The Chapel Island Formation is a sedimentary formation from the Burin Peninsula, Newfoundland, Canada. It is an over 1000 meter thick succession of siliciclastic deposits that were deposited during the latest Ediacaran and earliest Cambrian.
Sequence stratigraphy shown here: The formation starts in an intertidal zone, then as the Cambrian progresses, it becomes deeper water (outer shelf) as a general trend. The Chapel Island Formation lies on top of the Rencontre Formation and below the Random Formation. It is 900 m thick in Fortune Bay as a fault-bounded basin, ; grey-green siltstones and sandstones, with minor limestone beds near its top. Small Shelly Fossils have been recovered - primitive taxa only. Setting nearshore or open shelf.
The Formation is divided into six members, numbered 1 to 5, with member 2 split into 2A and 2B. The Proterozoic/Cambrian-boundary occurs 20.66 m above the base of the CIF, 2.4 m into Member 2A.
The lowest occurrence of T.pedum in the succession is 16.25 m above the base of the unit.Attention: This template is deprecated. Please use {{}} instead.
