Density of the ocean crust

Nature, 1984
The density structure and average density of the oceanic crust have implications for various geological and geophysical problems, including interpretations of gravity data, the variation of lithospheric bouyancy in relation to age, and role and fate of the crust in subduction.

Ophiolites and oceanic crust

Nature, 1974
OPHIOLITES consist of a pseudostratiform sequence, of harzburgite, tectonite, ultramafic and mafic cumulates sometimes including gabbro and quartz diorite (plagiogranite) intrusions, dolerite dyke swarms, pillow lava1, and deep-sea sediments2–4. This assemblage occurs in all Phanerozoic mountain systems and is interpreted as fossil oceanic crust and ...

Chemical alteration of the oceanic crust

Geologische Rundschau, 1989
The alteration of the upper oceanic crust through sea water-basement rock interaction produces different and distinct alteration zones with increasing depth. The zonation generally shows a consistent worldwide pattern.

The Process of Formation of Ocean Crust

Science, 1983
Ocean crust is the outermost layer of earth under the oceans. It is separated from the underlying mantle by a seismic transition zone called the Moho. A widely held view is that the Moho represents a petrologic change from basaltic-type rocks to a mantle composed mostly of olivine and pyroxene.
