The Mariana plate is a micro tectonic plate located west of the Mariana Trench which forms the basement of the Mariana Islands which form part of the Izu–Bonin–Mariana Arc. It is separated from the Philippine Sea plate to the west by a divergent boundary with numerous transform fault offsets.
The Izu–Bonin–Mariana (IBM) arc system is a tectonic plate convergent boundary in Micronesia.The IBM arc system extends over 2800 km south from Tokyo, Japan, to beyond Guam, and includes the Izu Islands, the Bonin Islands, and the Mariana Islands; much more of the IBM arc system is submerged below sealevel.
The Mariana Islands are the southern part of a submerged mountain range that extends 1,565 miles (2,519 km) from Guam to near Japan. Geographically, the Marianas are part of a larger region called Micronesia, situated between 13° and 21°N latitude and 144° and 146°E longitude. The Mariana Islands have a total land area of 1,008 km 2 (389 sq ...
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate.
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...
The Mariana Islands lie atop the largely submerged East Mariana Ridge, a part of the Izu–Bonin–Mariana (IBM) Arc. The IBM Arc is a tectonic plate convergent boundary where the west Pacific Plate subducts the Philippine Sea Plate. Guam is actually located on the Mariana Plate, a micro plate between the two.
The island chain arises as a result of the western edge of the Pacific Plate moving westward and plunging downward below the Mariana plate, a region that is the most volcanically active convergent plate boundary on Earth. The Marianas were politically divided in 1898, when the United States acquired title to Guam under the Treaty of Paris, 1898 ...
