Group (stratigraphy)
In geology, a group is a lithostratigraphy, lithostratigraphic Stratigraphic unit, unit consisting of a series of related Geological formation, formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into Supergroup (geology), supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distingui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods ( myriapods, arachnids and hexapods) ...

Whirlpool Sandstone
A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms ( ). ''Vortex'' is the proper term for a whirlpool that has a downdraft. In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. Smaller whirlpools appear at Rapids, river rapids and can be observed downstream of artificial structures such as weirs and dams. Large waterfall, cataracts, such as Niagara Falls, produce strong whirlpools. Notable whirlpools Saltstraumen Saltstraumen is a narrow strait located close to the Arctic Circle, south-east of the city of Bodø (town), Bodø, Norway. It has one of the strongest tidal currents in the world. Whirlpools up to in diameter and in depth are formed when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thorold Sandstone
Thorold is a city in Ontario, Canada, located on the Niagara Escarpment. It is also the seat of the Regional Municipality of Niagara. The Welland Canal passes through the city, featuring lock 7 and the Twin Flight Locks. History The first survey of Thorold, or Township 9 as it was known then, occurred in 1788. The earliest communities in what is now Thorold emerged at Beaverdams, DeCew Falls and St. Johns. In 1846, the community had a population of about 1,000 and there were three churches or chapels and a post office. Various types of tradesmen worked here. Industry included two grist mills, a cement mill, a brewery and three wagon makers. There were seven taverns. Thorold, located on the brow of the Niagara Escarpment, soon became dominant and was incorporated as a village in 1850. Its formation was linked to the creation of the First Welland Canal. The village experienced population growth as the canal became more developed. In 1875, Thorold became a town. When the Region ...

Cambria Shale
Cambria is a name for Wales, being the Latinised form of the Welsh name for the country, . The term was not in use during the Roman period (when Wales had not come into existence as a distinct entity) or the early medieval period. After the Anglo-Saxon settlement of much of Britain, a territorial distinction developed between the new Anglo-Saxon kingdoms (which would become England and Southern Scotland) and the remaining Celtic British kingdoms (which would become Wales and, before their absorption into England and Scotland, Cornwall to the south and Strathclyde or Hen Ogledd to the north). Latin being the primary language of scholarship in Western Christendom, medieval writers commonly used either the older term ''Britannia'', as the territory still inhabited by Britons, or ''Wallia'', a term derived from Old English, to refer to Wales. The term ''Cambria'' is first attested in Geoffrey of Monmouth in the 12th century as an alternative to both of these, since ''Britannia'' ...

Kodak Sandstone
The Eastman Kodak Company, referred to simply as Kodak (), is an American public company that produces various products related to its historic basis in film photography. The company is headquartered in Rochester, New York, and is incorporated in New Jersey. It is best known for photographic film products, which it brought to a mass market for the first time.
