  2. Mid-ocean ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-ocean_ridge

    Mid-ocean ridge cross-section (cut-away view) 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.

    en.wikipedia.org/wiki/British_Mid-Ocean_Ridge...

    The British Mid-Ocean Ridge Initiative (the BRIDGE Programme) was a multidisciplinary scientific investigation of the creation of the Earth's crust in the deep oceans. It was funded by the UK's Natural Environment Research Council ( NERC ) from 1993 to 1999.

  4. Charlie–Gibbs fracture zone - Wikipedia

    en.wikipedia.org/wiki/Charlie–Gibbs_fracture_zone

    The Charlie–Gibbs fracture zone has large amounts of mid-ocean ridge igneous and metamorphic rocks. [ 3 ] : 2 At the eastern termination off shore of Newfoundland there is an igneous province found within the otherwise nonvolcanic rifted margin in the region of transition between oceanic and continental crust.

  5. Magmatism along strike-slip faults - Wikipedia

    en.wikipedia.org/wiki/Magmatism_along_strike...

    Magmatism along strike-slip faults is the process of rock melting, magma ascent and emplacement, associated with the tectonics and geometry of various strike-slip settings, most commonly occurring along transform boundaries at mid-ocean ridge spreading centres [1] and at strike-slip systems parallel to oblique subduction zones. [2]

  6. List of fracture zones - Wikipedia

    Major fractures zones of the Atlantic can be seen on this ocean depth map Active Atlantic Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region In the Atlantic Ocean most fracture zones originate from the Mid-Atlantic Ridge , which runs from north to south, and are therefore west to east oriented ...

  7. Fifteen-Twenty fracture zone - Wikipedia

    en.wikipedia.org/wiki/Fifteen-Twenty_Fracture_Zone

    Corrugated surfaces known as megamullions or oceanic core complexes measure 25 km (16 mi) along-axis and 10–15 km (6.2–9.3 mi) across. When found along other mid-ocean ridges such structures occur at the inside corners of ridge discontinuities, but at the FTFZ they occur on both sides of the ridge away from any non-transform discontinuities.

  9. Vine–Matthews–Morley hypothesis - Wikipedia

    en.wikipedia.org/wiki/Vine–Matthews–Morley...

    Magnetic anomalies off west coast of North America. Dashed lines are spreading centers on mid-ocean ridges. The Vine–Matthews-Morley hypothesis correlates the symmetric magnetic patterns seen on the seafloor with geomagnetic field reversals. At mid-ocean ridges, new crust is created by the injection, extrusion, and solidification of magma.
