The Bull Arm Formation is a volcanic formation cropping out in Newfoundland, the youngest of the Musgravetown Group. [3] 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.

New Chelsea-New Melbourne-Brownsdale-Sibley's Cove-Lead Cove is a local service district and designated place in the Canadian province of Newfoundland and Labrador.
John Bicknell Auden was an English geologist and explorer, older brother of the poet W. H. Auden, who worked for many years in India with the Geological Survey of India and later with the Food and Agriculture Organization. He studied the Himalayan strata, particularly the Krol Belt where he recognized rocks from the Peninsula thrusting north into the Himalayas. He also studied groundwater and was involved in studying the geology of many dam sites in India. Auden's Col is named after him.
The Baie Verte Peninsula is a large peninsula on the north central coast of the island of Newfoundland in the Canadian province of Newfoundland and Labrador.
Smith Sound is a zigzag 24 kilometre 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.
Newfoundland is a large island within the Canadian province of Newfoundland and Labrador. It is situated off the eastern coast of the North American mainland and the geographical region of Labrador.
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.
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.
The St John's Group is a fossiliferous shale-dominated Ediacaran geologic group in Newfoundland and Labrador, younger than 565 ± 3 million years ago.
The Uzboi-Landon-Morava (ULM) outflow system is a long series of channels and depressions that may have carried water across a major part of Mars. It starts with channels that drain into the Argyre basin in the Argyre quadrangle. Water ponded in the Argyre basin, then the overflow is believed to have traveled northward through Uzboi Vallis, into Landon basin, through Morava Valles, to the floor of Margaritifer basin. Some of the water may have helped to carve Ares Vallis. Altogether, the total area drained for this watershed may have been about 11 X 106 km2 or about 9% of Mars.
The Random Formation is a rock unit in Newfoundland dating to the early Cambrian period, dominated by tidal quartz arenites deposited in a near-shore environment, 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 (574 ft) 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 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 Middle Cambrian (Drumian) geological formation cropping out in the Random Island area of Newfoundland and elsewhere?. Its black/dark brown, finely laminated mudstones and thicker-bedded siltstones are occasionally interrupted by thin yellowish silty limestone horizons.
The Connecting Point Group is a Late Neoproterozoic geological formation cropping out on the Avalon Peninsula of Newfoundland, dominated by deep marine turbidite deposits.
The Musgravetown Group is a terminal Ediacaran stratigraphic group of terrestrialish sandstones, lavas and tuffs cropping out in Newfoundland.
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.
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.
The geology of Newfoundland and Labrador includes basement rocks formed as part of the Grenville Province in the west and Labrador and the Avalonian microcontinent in the east. Extensive tectonic changes, metamorphism and volcanic activity have formed the region throughout Earth history.
The Gangapur Formation is a geological formation in Telangana, India. The Gangapur formation is Early Cretaceous in age. It forms a part of the Pranhita–Godavari Basin and overlies the Jurassic Kota Formation. The outcrops near the Gangapur village was first described in 1881 as the Gangapur beds. In 1969, the area was instituted as the Gangapur Formation. It was also determined that the Gangapur Formation extends from north of Nowgaon to the west of Gangapur and in the east up to Dharmaram and Paikasigudem. Fossils of Plants have been found in large quantities in the formation.
