Occurrence of the Rocky Harbour Formation in southeastern Newfoundland [1]

The Rocky Harbour Formation is a formation cropping out in Newfoundland. Its depositional setting was deltaic, with sediments showing the influence of tides and waves. [2]

Bell Island (Newfoundland and Labrador) island in Newfoundland and Labrador, Canada

Bell Island is an island located off the Avalon Peninsula of Newfoundland and Labrador, Canada in Conception Bay. Measuring 9.7 kilometres (6.0 mi) in length and 3.5 kilometres (2.2 mi) in width, it has an area of 34 square kilometres. The subsurface is composed of Ordovician sandstone and shale with red hematite. It was once the site of large iron ore mines.

Burgeo-La Poile is a provincial electoral district for the House of Assembly of Newfoundland and Labrador, Canada. As of 2011, there are 7,527 eligible voters living within the district. The district was first created in 1995 following a reduction in the number of seats in the House of Assembly from 52 to 48, forming from the amalgamation of the former districts of La Poile and Burgeo-Bay D'Espoir.

Fortune Bay Newfoundland, Canada

Fortune Bay is a fairly large natural bay located in the Gulf of St. Lawrence on the south coast of Newfoundland, Canada. The Bay is bounded by Point Crewe on the Burin Peninsula and Pass Island at the entrance to Hermitage Bay to the northwest for a distance of 56 kilometers. The bay extends in a northeast direction for 105 kilometers ending at Terrenceville.

Smith Sound, Newfoundland and Labrador

Smith Sound is a zigzag 24 kilometer inner region of Trinity Bay. This sound is one of the longest portions of inshore waterways in Newfoundland, located on its north-eastern coast in the Canadian province of Newfoundland and Labrador. Bonavista Peninsula is to the north of the sound, while Random Island is to the south. The waters that make up the sound is a continuous channel that encircles Random Island, broken only by a narrow channel located at Clarenville where a causeway was built to provide access to the communities on Random Island. The channel on the south side of Random Island is North West Arm.

Jeanne dArc Basin

The Jeanne d'Arc Basin is an offshore sedimentary basin located about 340 kilometres to the basin centre, east-southeast of St. John's, Newfoundland and Labrador. This basin formed in response to the large scale plate tectonic forces that ripped apart the super-continent Pangea and also led to sea-floor spreading in the North Atlantic Ocean. This basin is one of a series of rift basins that are located on the broad, shallow promontory of continental crust known as the Grand Banks of Newfoundland off Canada's east coast. The basin was named after a purported 20 metres shoal labelled as "Ste. Jeanne d'Arc" on out-dated bathymetric charts and which was once thought to represent a local exposure of basement rocks similar to the Virgin Rocks.

Chamberlains Brook Formation

The Chamberlain's Brook Formation is a thin but distinctive geologic formation of dark red calcareous mudstones that crops out from Rhode Island to Massachusetts and, Nova Scotia, New Brunswick and Newfoundland. It preserves fossils, including trilobites, dating back to the lower mid-Cambrian period. Its lowermost member is the Braintree Member and the uppermost member is the Fossil Brook Member.

The Brigus Formation is a fossiliferous upper lower Cambrian geologic formation in Newfoundland and Labrador.

Random Formation

The Random Formation is a near-shore rock unit dating to the early Cambrian period, dominated by tidal quartz arenites, but also incorporating intertidal and open-shelf deposits, including glauconitic and mud-cracked mudstones, and red channel sandstones. It was deposited quickly and is approximately 175 m thick. The Blue Pinion Formation was originally recognized as a separate formation, but is now interpreted as an expression of the Random Formation.

The Smith Point Formation is an Early Cambrian, fossil-rich, pink to brick red limestone formation cropping out in Newfoundland.

Crown Hill Formation

Crown Hill Formation is a late Ediacaran volcanic non-marine sedimentary formation in Newfoundland. It's topped off with a bright red conglomerate, with silt and arkose sands of similar hue too.

Manuels River Formation is a Cambrian geological formation cropping out in the Random Island area of Newfoundland. Its black/dark brown, finely laminated mudstones and thicker-bedded siltstones are occasionally interrupted by thin yellowish silty limestone horizons.

Connecting Point Group

The Connecting Point Group is a Late Neoproterozoic geological formation cropping out on the Avalon Peninsula of Newfoundland, dominated by deep marine turbidite deposits.

Musgravetown Group

Love Cove Group

The Love Cove Group is a metamorphosed volcaniclastic sedimentary group cropping out in southeastern Newfoundland. Strata from towards the middle of the formation have been dated to 620 ± 1 million years ago.

Bull Arm Formation

The Bull Arm Formation is a volcanic formation cropping out in Newfoundland, the youngest of the Musgravetown Group. It is defined as everything between the first and last volcanic horizon, with a recognition that some sandstones will be interbedded, and its start and finish may vary across the region depending on how widespread volcanic horizons are in practice.
