Pacific ocean crustidges, at volcanic seamounts near these spreading axes and at active hot-spots. Elsewhere, the Pacific Ocean is floored by sediments that have accumulated on older oceanic crust and on several types of abundant volcanic constructions (Figure 11.1).

FIN

Book 1991ularly since the concept of sea-floor spreading became widely accepted. This book provides a review of these rocks, first dicussing how we sample the ocean floor and what we know about the structure of the oceanic crust, followed by an overview of the various regional settings (Pacific crust, Atlant

Experimental phase petrology of mid-ocean ridge basaltsn equilibrium with basaltic liquids under a variety of magmatic conditions. These experimental studies generally fall into two major groups, those at low pressures (generally at 1 atm (1 atm = 101 325 N m .), but sometimes 2-3 kbar (1 bar = 10. N m .)) and those at high pressures (generally about 8-30 kbar).
