Introduction and the ophiolite modelnd the Mediterranean islands. When Darwin landed on St Paul’s Rocks in the equatorial Atlantic from the . in 1831, he could recognize the anomaly of the peridotite mylonites that he found there. These mylonites are the only subaerial outcrop of an active oceanic transform fault zone, although that p

Structure of the oceanic crust as deduced from ophiolitese and there are limitations to the depths penetrable by drilling (currently about 1 km below the seafloor). Our current knowledge of crustal structure is based on three sources of information: (1) rock samples obtained by submersibles and from oceanic islands, drill core and dredge hauls; (2) geophy

Mineralogy and crystallization of oceanic basaltsce on our planet, covering nearly two-thirds of the earth’s surface beneath the oceans. Three decades ago, the lavas of the oceanic ridges were virtually unknown and unsampled. Today, major portions of the ocean ridge system in the Atlantic, Pacific and Indian Oceans have been dredged, drilled and s

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 8–3

Magmatic processes in oceanic ridge and intraplate settingsThe oceanic lithosphere also contains islands and archipelagos representing the effects of isolated, but durable, mantle melting anomalies. In attempting to review the processes of magma genesis and evolution in these distinctive environments, this chapter draws on existing syntheses of magmatic pro

Metamorphic and hydrothermal processes: basalt—seawater interactions. Part II of this book discusses the importance of many of these initial basalt properties and how their measurement can be interpreted to infer the source, melting history, magmatic evolution and volcanic processes which formed the oceanic basalts. This chapter discusses how these properties can be
