The Central Basin Platform (CBP) is a tectonically uplifted basement block capped by a carbonate platform. The CBP separates the Delaware and Midland Basins and is subdivided into several formations, from oldest to youngest Neal Ranch , Lennox Hills , Abo , Yeso , Glorieta , San Andres , Grayburg , Queen , Seven Rivers , Yates , and Tansill ...
The narrow central section west of this graben system carries stratovolcanoes like the Cantal – Europe's highest shield volcano – and the Monts Dore (including the highest elevation in the massif, the Puy de Sancy), but also maar and explosion craters of the Chaîne des Puys farther north.
[15]: [26] There are two basins the large South Permian Basin, and the smaller Northern Permian basin, which are east–west trending. The basins are separated by the Ringkøbing-Fyn system of highs. [1]: [47] The Viking Graben lies between the Shetland Platform and the Fenno-Scandian high. The Central Graben lies amid the Permian basins and ...
Foreland basin systems comprise three characteristic properties: An elongate region of potential sediment accommodation that forms on continental crust between a contractional orogenic belt and the adjacent craton, mainly in response to geodynamic processes related to subduction and the resulting peripheral or retroarc fold-thrust belt;
Basement rock is the thick foundation of ancient, and oldest, metamorphic and igneous rock that forms the crust of continents, often in the form of granite. [2] Basement rock is contrasted to overlying sedimentary rocks which are laid down on top of the basement rocks after the continent was formed, such as sandstone and limestone. The ...
The Benue Trough was formed by rifting of the central West African basement, beginning at the start of the Cretaceous period. [fn 1] At first, the trough accumulated sediments deposited by rivers and lakes. During the Late Early to Middle Cretaceous, the basin subsided rapidly and was covered by the sea.
[4] [5] Triassic outcrops are exposed in a long and narrow belt between pre-Triassic sediments along the west coast and the post-Triassic sediments of the central basin. The Triassic rock units are divided into the Sassendalen Group , dating from Early Triassic to Late Middle Triassic, and the succeeding Kapp Toscana Group .
Under the Philippine Sea lie a number of basins including the West Philippine Basin, inside of which is located the Central Basin Fault (CBF). [7] Philippine Rise is located in the CBF and its geologic basement is probably a micro-continent. [8]
