Layering of Oceanic Crust

2014
Magma generated by decompression melting of the upwelling mantle beneath mid-ocean ridges (MORs) rises buoyantly and accumulates in crustal magma chambers (e.g., Forsyth, 1992). The long-held view is that oceanic crust is built from in situ crystallization of melts in these reservoirs, as well as from melts extracted from the magma chamber(s) in the ...

Oceanic Crust and Mantle

1988
The Nd isotopic data provide an important addition to petrogenetic modeling studies of igneous rocks because they provide previously unavailable information about the chemical composition of magma sources. Oceanic basalts present the possibility of applying the isotopic data for this purpose in a relatively straightforward way because there is little ...

Generation of Oceanic Crust

1989
Significant differences between ophiolites (table 8.1) led us to distinguish a harzburgite ophiolite type (HOT) and a lherzolite ophiolite type (LOT) which were ascribed respectively to fast and slow spreading situations (chapter 8). Similarly, significant differences between fast and slow spreading ridges encourage comparisons with these two types of ...

The mantle and oceanic crust

1993
The mantle contains 84% of the volume and 68% of the mass of the Earth, but because it is separated from direct observation by the thin crust — only about 6 km thick beneath the oceans and an average of 35 km beneath the continental surface — there are many unsolved problems.

Metallogeny of Oceanic-Type Crust

1984
The volumes of magma generated per year along the current < 50 000-km-long system of oceanic spreading ridges are estimated to exceed that of the remainder of the earth by about one order of magnitude (Menard 1967). Oceanic crust and lithosphere are mainly formed at so-called midocean ridge systems, but essentially similar oceanic crust is also ...
