Exposure of the Sandrock Formation on the southern half of the Isle of Wight

The Sandrock Formation is a geological formation in England, part of the Lower Greensand Group, it is found on the Isle of Wight and in the northern part of Swanage Bay. It consists of a cyclic rhythm of sandstones, siltstones, and mudstones. [1]

Alluvium Loose soil or sediment that is eroded and redeposited in a non-marine setting

Alluvium is loose, unconsolidated soil or sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel. When this loose alluvial material is deposited or cemented into a lithological unit, or lithified, it is called an alluvial deposit.

Permian Basin (North America) Sedimentary basin in the United States with large mineral and fossil fuel deposits

The Permian Basin is a large sedimentary basin in the southwestern part of the United States. The basin contains the Mid-Continent Oil Field province. This sedimentary basin is located in western Texas and southeastern New Mexico. It reaches from just south of Lubbock, past Midland and Odessa, south nearly to the Rio Grande River in southern West Central Texas, and extending westward into the southeastern part of New Mexico. It is so named because it has one of the world's thickest deposits of rocks from the Permian geologic period. The greater Permian Basin comprises several component basins; of these, the Midland Basin is the largest, Delaware Basin is the second largest, and Marfa Basin is the smallest. The Permian Basin covers more than 86,000 square miles (220,000 km2), and extends across an area approximately 250 miles (400 km) wide and 300 miles (480 km) long.

Old Red Sandstone Assemblage of rocks in the North Atlantic region

The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica/Laurussia. In Britain it is a lithostratigraphic unit to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain.

Alberto Juantorena Cuban runner

Alberto Juantorena is a Cuban former runner. He is the only athlete to win both the 400 and 800 m Olympic titles, which he achieved in 1976. He was ranked as world's best runner in the 400 m in 1974 and 1976–1978, and in the 800 m in 1976–77, and was chosen as the Track & Field News Athlete of the Year in 1976 and 1977.

Geology of the Grand Canyon area Scientific rock study of the Grand Canyon, Arizona

The geology of the Grand Canyon area includes one of the most complete and studied sequences of rock on Earth. The nearly 40 major sedimentary rock layers exposed in the Grand Canyon and in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. Most were deposited in warm, shallow seas and near ancient, long-gone sea shores in western North America. Both marine and terrestrial sediments are represented, including lithified sand dunes from an extinct desert. There are at least 14 known unconformities in the geologic record found in the Grand Canyon.

Ellsworth Mountains highest mountain ranges in Antarctica

The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 360 km (224 mi) long and 48 km (30 mi) wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson (4,892 m) constituting the highest point on the continent. Geologically, they are part of the Antarctandes which stretch from the Antarctic Peninsula to Cape Adare on the western shore of the Ross Sea. The Antarctandes form the southernmost arc of the Pacific 'Ring of Fire'. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones.

Geological formation The fundamental unit of lithostratigraphy

A geological formation, or formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguish it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region. It is the fundamental unit of lithostratigraphy, the study of strata or rock layers.

The Rupie was the currency of German East Africa between 1890 and 1916, continuing to circulate in the Tanganyika Territory until 1920.

Group (stratigraphy) stratigraphic unit, smaller than a supergroup and larger than a subgroup

A group is a lithostratigraphic unit, a part of the geologic record preserved in rock strata. Groups are generally divided into individual formations. Groups may sometimes be combined into supergroups.

The Lias Group or Lias is a lithostratigraphic unit found in a large area of western Europe, including the British Isles, the North Sea, the Low Countries and the north of Germany. It consists of marine limestones, shales, marls and clays.

The Punchbowl Formation is a sedimentary sandstone geologic formation in the northern San Gabriel Mountains, above the Antelope Valley in Los Angeles County, southern California.

The geology of West Sussex in southeast England comprises a succession of sedimentary rocks of Cretaceous age overlain in the south by sediments of Palaeogene age. The sequence of strata from both periods consists of a variety of sandstones, mudstones, siltstones and limestones. These sediments were deposited within the Hampshire and Weald basins. Erosion subsequent to large scale but gentle folding associated with the Alpine Orogeny has resulted in the present outcrop pattern across the county, dominated by the north facing chalk scarp of the South Downs. The bedrock is overlain by a suite of Quaternary deposits of varied origin. Parts of both the bedrock and these superficial deposits have been worked for a variety of minerals for use in construction, industry and agriculture.
