Mid-Atlantic Ridge, submarine ridge lying along the north-south axis of the Atlantic Ocean; it occupies the central part of the basin between a series of flat abyssal plains that continue to the margins of the continental coasts.The Mid-Atlantic Ridge is in effect an immensely long mountain chain extending for about 10,000 miles (16,000 km) in a curving path from the Arctic Ocean to near the ...

Map of the Mid-Ocean Ridges. Andrew Alden is a geologist based in Oakland, California. He works as a research guide for the U.S. Geological Survey. Almost entirely hidden under the sea is a worldwide chain of low mountains with lines of volcanic activity running along their crests. Their worldwide extent was recognized in the mid-20th century ... Mid Ocean Ridge (MORB) Mid ocean Ridges are the most prominent producers of magma globally. The magma is produced by decompression melting, which occurs when two plates move away from each other. This tectonic boundary is a Divergent Boundary. Typically it produces oceanic crust and typically occurs in oceanic crust settings. away from the ridges.

Mid ocean ridge diagram. A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics.It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin.This feature is where seafloor spreading takes place along a divergent plate boundary.The rate of seafloor spreading determines the morphology of the crest of the mid-ocean ... Mid-ocean ridge magmas from slow ridges also pond on average at greater and more variable depths and undergo less homogenization than those from fast ridges. These features are consistent with LOC accretion resembling the "multiple sills" model at slow ridges. In contrast, shallow magma ponding and limited hydrothermal alteration in LOC at ... Block diagram of a slow-spreading mid-ocean ridge segment, including the oceanic crust and lithosphere. Note the high-angle normal faulting and rifted nature of the ridge axis. At mid-ocean ridge segment ends and accommodation zones, extension is accommodated amagmatically on low-angle normal faults and oceanic core complexes (OCC) are formed.

A mid-ocean ridge is a zone where new seafloor is constantly created due to the welling of molten rock from beneath the earth’s surface. To understand why mid-ocean ridges form, it’s helpful to understand a few basics of plate tectonics. The earth’s mantle is made of molten rock, or magma, that is constantly in motion beneath the crust. The mid-ocean ridge is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying in the deep ocean. The nearly continuous, global mid-ocean ridge system snakes across the Earth’s surface like the seams on a baseball. Iceland is unique in that many researchers believe that a mantle plume is rising up through the Mid-Atlantic Ridge here. Thus melting at Iceland probably involves both high-temperature melting due to a thermal anomaly and decompression melting related to the divergent boundary. This may explain why eruption rates are so high (a significant eruption occurs once every 2-3 years), and why it is ... A big picture cross section showing melt (molten rock) in the upper mantle beneath the East Pacific Rise. Melt extends over 100 kilometers deep below oceanic crust, and spans a breadth of several hundred kilometers.

A mid-ocean ridge marks the location where molten magma and lave are moving up, cooling, and forming new ocean floor. The zones of normal magnetization are indicated by ///// shading of the oceanic crust. The figure below shows the observed magnetic pattern along the mid-Atlantic Ridge south of Iceland. Mattox (1992) summary, the highest segments of the oceanic crusts documented above share many similarities to the mid- ocean ridges in Figure 2 and the craterlike features ... the feature is a mid-ocean ridge, a mountain range that extends along the ocean floor name the process occurring at B and explains what it results from it. the process is sea-floor spreading. it continually adds new material to the ocean floor The East Pacific Rise is a mid-ocean ridge that runs through the eastern Pacific Ocean and separates the Pacific plate from the North American plate, the Cocos plate, the Nazca plate, and the Antarctic plate. The Southeast Indian Ridge marks where the southern Indo-Australian plate forms a divergent boundary with the Antarctic plate.

The oldest parts of the oceanic crust are found farest from the mid ocean ridges at subduction zones and continental shelves. New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust is.

Midoceanic ridges

Samples of a primitive mid-ocean ridge basalt (MORB) glass were encapsulated in a mixture of ol (Fo90) and opx (En90) and melted at 10, 15, and 20 kbar. After quenching, the basaltic glass was present as a pool within the ol + opx capsule, but its composition had changed so that it was saturated with ol and opx at the conditions of the experiment.
