Mid-Atlantic RidgeThe Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate boundary located along the floor of the Atlantic Ocean, and the longest mountain range in the world. It separates the Eurasian Plate and North American Plate in the North Atlantic, and the ...

大西洋洋中脊(又称大西洋中洋脊;英文:Mid-Atlantic Ridge)是一个大部分地区位于海底的山脉,横跨大西洋及北冰洋。大西洋洋中脊由北纬87度(距离北极333公里)伸延至南纬54度的布韦岛。大西洋中脊的最高点突出海面,形成海岛。大西洋洋中脊为全球洋中脊(Mid-ocean ridge)系统的一部分,其形成方式亦被认为与其他洋中...
Mantle flow velocities were estimated assuming steady-state plate-thickening passive flow64 beneath a ridge-transform-ridge plate boundary simulating the Vema transform geometry. Red thick dashed lines indicate boundaries between garnet and spinel stability fields. Mineral proportions in the transition zone...
Noun1.Mid-Atlantic Ridge- a very long narrow elevation on the ocean floor that runs all the way from Iceland in the North Atlantic to Bouvet Island in the South Atlantic Atlantic,Atlantic Ocean- the 2nd largest ocean; separates North and South America on the west from Europe and Africa on...
The deep subvertical detachment fault roots on the plate boundary, marked by a thermal anomaly and transient magma bodies. Thermal and magmatic variations control the structure and morphology of the seafloor above the subhorizontal detachment surface, occasionally leading to relocating the detachment....
where, in accordance withplate tectonictheory,lithospheric plates(also called tectonic plates) move apart and new crust is created by magma (molten rock) pushing up from themantle. The mid-ocean ridge system is an example of a divergent (rather than a convergent or transform) plate boundary. ...
