0 the part of the outer rocky layer of the earth that is under the oceans and is thinner than the layer under the land
This, combined with the young age of the oceanic crust, explains why few craters are likely to be found in the oceans.
The detached amphibolitized oceanic crust may then return to shallow depths as a result of its positive buoyancy against the denser surrounding mantle.
The basement is thought to be oceanic crust, generated either at a mid-ocean ridge or by back-arc spreading dependent on the favoured model.
The progressive contraction of oceanic crust caused the uplift of previously rifted continental margin and platforms and the formation of foredeep flysch basins.
Recycling of hydrated basalt of the oceanic crust and growth of early continents.
Fortunately, some portions of oceanic crust are occasionally preserved as ophiolites.
The progressive contraction of oceanic crust caused the uplift of previously rifted continental margin and platforms, and formation of foredeep flysch basins.
The majority of the oceanic crust formed today is created at intermediate- to fast-spreading ocean ridges.
