Ophiolites are created under mid-ocean ridges and represent a vertical section beneath a ridge system. One of the best ophiolites is seen in the Troodos range in Southern Cyprus. The topmost layer is invariably pillow lavas which are usually basaltic lavas that were erupted under water.
Then as an ocean closes due to subduction, part of the ocean ridge system MAY be scrapped off and by a process called OBDUCTION be forced onto the plate which is over-riding which is usually the continental plate. If the processes cause the obducted mass to rise above sea level the result is an ophiolite.
So whilst they are created at mid-ocean ridges they are the result of subduction.

What do volcanic belts form along on?
Both subduction zones and spreading centers.
How did st Helen's form?
It was formed from converget bounderies.
How did mt st Helen form?
It was formed from converget bounderies.
Which is required for an ocean trench to form?
Subduction.
Hotspot volcanoes occur along subduction zones?
False. Hotspot volcanoes form above mantle plumes, which are localized upwellings of hot mantle material. Subduction zone volcanoes form due to the subduction of one tectonic plate beneath another, resulting in magma generation due to the melting of the subducted plate.
What kind of volcanoes form along subduction zones?
Composite or stratovolcanoes typically form along subduction zones. These volcanoes are characterized by their steep-sided profile, explosive eruptions due to the presence of viscous magma, and alternating layers of lava flows and volcanic ash. Subduction zones are where one tectonic plate slides beneath another plate, leading to magma formation and volcanic activity.
What boundary do subduction zones form on?
Subduction zones form along some tectonic plate boundaries. Of the three general types of tectonic plate boundaries, we will see them form at some (but not all) of what are called convergent plate boundaries.
Why do strong earthquakes occur?
In subduction zones, the scraping lithosphere can form a ridged springboard that is loaded by the subducting lithosphere. When the load is enough to overcome the friction of subduction, it can unload within minutes causing massive earthquakes along the fault.
What 2 bodies of water form the southern and eastern bounderies of new England?
a ocean and a lake
How are subduction form?
by plate tectonics
What forms at a subduction zone?
Volcanic arcs and oceanic trenches commonly form at subduction zones.
Did japan form as a result of subduction or a hot spot?
Japan formed as a result of a subduction zone.
