Tectonically, studied lithologies from NHO correspond to a boninitic to slab-proximal Island Arc Tholeiite affinity thereby conforming to an intraoceanic supra subduction zone (SSZ) fore-arc regime coherent with the subduction initiation process. The geochemical attributes for the crustal and mantle ...
subduction zone,oceanic trencharea marginal to a continent in which, according to the theory ofplate tectonics, older and denser seafloor underthrusts the continental mass, dragging downward into theEarth’supper mantle the accumulated trench sediments. The subduction zone, accordingly, is theantithesis...
Oceanic crustis created asmagmarises to fill the gap between divergingtectonic platesand is consumed insubduction zones. It is geologically young, with a mean age of 60Ma, and is thin, averaging 6.5km in thickness. Oceanic crust consists almost exclusively of extrusivebasaltand its intrusive equiv...
Known examples of oceanic plateau subduction include the Cretaceous Caribbean Plateau, accreting at and subducting/underthrusting beneath the Greater Antilles on the Caribbean Plate and the south-eastern part of the Ontong Java Plateau presently subducting beneath the Solomon Islands at the north Solomon...
