The Caribbean plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the northern coast of South America. Roughly 3.2 million square kilometres (1.2 million square miles) in area, the Caribbean plate borders the North American plate, the South American plate, the Nazca plate and the Cocos plate.
Into the Paleogene at the start of the Cenozoic, volcanism, metamorphism and plutonism continued underwater until the Eocene, still largely below water.However, by the middle Eocene, the amalgamated island arcs collided with the southern margin of the North American Plate at the Florida-Bahama Platform, leading to the formation of extensive carbonates and the end of volcanism and plutonism.
Divergence between the North American and South American Plates began to create oceanic crust off Colombia's Pacific coast by the end of the Jurassic (150 Ma). This divergence, which continued until at least 66 Ma, first resulted in a "proto-Caribbean spreading ridge" between these plates flanked by a perpendicular transform zone on its Pacific side.
The Gonâve microplate, showing location of the main fault zones. The Septentrional–Orient fault zone (SOFZ) is a system of active coaxial left lateral-moving strike slip faults that runs along the northern side of the island of Hispaniola where Haiti and the Dominican Republic are located and continues along the south of Cuba along the northern margin of the Cayman Trough.
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
The EPGFZ shares approximately half of the relative motion between the North American and Caribbean tectonic plates with the Septentrional-Oriente fault zone which runs along the northern side of Hispaniola. Both faults merge into the Cayman Trench to the west.
Caribbean plate map. The boundaries of the Caribbean plate showcase a variety of intricate tectonic interactions involving four significant neighboring plates: the North American plate, South American plate, Nazca plate, and Cocos plate. To the north, the North American plate moves westward at a rate of roughly 20 mm per year.
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 causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
