Formation (geology)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob ...

Geography Of Barbados
Barbados is a continental island in the North Atlantic Ocean and is located at 13°10' north of the equator, and 59°32' west of the Prime Meridian. As the easternmost isle of the Lesser Antilles in the West Indies, Barbados lies 160 kilometres (100 mi) east of the Windward Islands and Caribbean Sea. The maritime claim for Barbados is a territorial sea of , with an exclusive economic zone of which gives Barbados a total maritime area of . Of the total EEZ area, 70,000 km2 is set aside for offshore oil exploration. A pending application to UNCLOS has placed for consideration a continental shelf to the east and south (or to the edge of the continental margin). To the west, most of Barbados' maritime boundaries consist of median lines with neighbours. These neighbours include: Martinique, and Saint Lucia to the northwest, Saint Vincent and the Grenadines to the west, Trinidad and Tobago and Venezuela to the southwest, and Guyana to the southeast. Barbados' total land a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paleogene Caribbean
The Paleogene Period ( ; also spelled Palaeogene or Palæogene) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period Ma (million years ago) to the beginning of the Neogene Period Ma. It is the first period of the Cenozoic Era, the tenth period of the Phanerozoic and is divided into the Paleocene, Eocene, and Oligocene epochs. The earlier term Tertiary Period was used to define the time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use. Paleogene is often abbreviated "Pg", although the United States Geological Survey uses the abbreviation "" for the Paleogene on the Survey's geologic maps. Much of the world's modern vertebrate diversity originated in a rapid surge of diversification in the early Paleogene, as survivors of the Cretaceous–Paleogene extinction event took advantage of empty ecologica ...

Geology Of Barbados
The geology of the island Barbados includes exposures of reef-related carbonate rocks spanning 85 percent of the island's surface. This coral rock formation is 70 meters thick and dates to the Pleistocene. Unlike neighboring islands in the Lesser Antilles volcanic arc, Barbados is unusual because it is not a volcanic island (the only volcanic rocks are some ash beds from eruptions on neighboring islands). Instead, the island of Barbados is the exposed part of the Barbados Ridge Accretionary Prism, left as deep ocean sediments "scraped" to the surface as the Atlantic oceanic crust subducted beneath the Caribbean Plate. The oldest rocks are in the Scotland Formation and include Eocene age turbidite and radiolarites. This unit is 4.5 kilometers thick from the sea floor to the surface. It is overlain by a syncline basin called the Woodbourne Trough, which includes pelagic sediments.

Geologic Formations Of The Caribbean
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Period (geology)
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardised international units of geological time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely ...

Early Eocene
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
