This, combined with the young age of theoceaniccrust, explains why few craters are likely to be found in the oceans.From theCambridge English Corpus
 The detached amphibolitizedoceaniccrustmay then return to shallow depths as a result of its positive buoyancy against the denser surrounding mantle.From theCambridge English Corpus
 The basement is thought to beoceaniccrust, generated either at a mid-ocean ridge or by back-arc spreading dependent on the favoured model.From theCambridge English Corpus
 The progressive contraction ofoceaniccrustcaused the uplift of previously rifted continental margin and platforms and the formation of foredeep flysch basins.From theCambridge English Corpus
 Recycling of hydrated basalt of theoceaniccrustand growth of early continents.From theCambridge English Corpus
 Fortunately, some portions ofoceaniccrustare occasionally preserved as ophiolites.From theCambridge English Corpus
 The progressive contraction ofoceaniccrustcaused the uplift of previously rifted continental margin and platforms, and formation of foredeep flysch basins.From theCambridge English Corpus
 The majority of theoceaniccrustformed today is created at intermediate- to fast-spreading ocean ridges.From theCambridge English Corpus
 This book contains a wealth of new data and new thinking on the whole problem of ophiolites andoceaniccrustand upper mantle.From theCambridge English Corpus
 The students, whilst acknowledging excellent texts in igneous petrology or igneous geochemistry, felt the lack of a multi-disciplinary text specifically covering the generation and evolution of theoceaniccrust.From theCambridge English Corpus
 Bioalteration of basaltic glass in theoceaniccrust.From theCambridge English Corpus
 These pressures are equivalent to 57-46 km depth beneath anoceaniccrust-mantle hanging-wall, a much greater thickness than can be accounted for by the thickness of the ophiolite.From theCambridge English Corpus
 Partial melting of subductingoceaniccrust.From theCambridge English Corpus
 The evidence of hornblende crystallization implies that the ultramafites and associated gabbros were emplaced at depth in a crust considerably thicker than typicaloceaniccrustas represented by ophiolites.From theCambridge English Corpus
