The formation of abyssal serpentinites leads to deep changes of the oceanic lithosphere
rheology and geochemistry, hence playing a key role on geodynamic and geochemical …

Tethyan ophiolites show an apparent poorly organized association of ultramafic and mafic
rocks. By contrast to the complete mantle-crustal sections of Semail-type ophiolite sheets …

Mid-ocean ridge basalts (MORB) provide fundamental information about the composition
and melting processes in the Earth's upper mantle. To use MORB to further our …

Mid-ocean ridge basalt (MORB) is the most abundant magma on Earth, and provides a
geochemical window into the mantle. Deriving mantle composition and melting processes …

Kane Megamullion, an oceanic core complex near the Mid-Atlantic Ridge (MAR) abutting
the Kane Transform, exposes nearly the full plutonic foundation of the MARK paleo-ridge …

The architecture of lower oceanic crust at slow-and ultraslow-spreading ridge is diverse, yet
the mechanisms that produce this diversity are not well understood. Particularly, the 660 …

Oceanic core complexes expose lower crustal and upper mantle rocks on the seafloor by
tectonic unroofing in the footwalls of large-slip detachment faults. The common occurrence …

This paper presents the first detailed geologic map of in situ lower ocean crust; the product
of six surveys of Atlantis Bank on the SW Indian Ridge. This combined with major and trace …

Abstract The Oman Drilling Project “Multi‐Borehole Observatory”(MBO) samples an area of
active weathering of tectonically exposed peridotite. This article reviews the geology of the …

Abstract 809 deep IODP Hole U1473A at Atlantis Bank, SWIR, is 2.2 km from 1,508‐m Hole
735B and 1.4 from 158‐m Hole 1105A. With map**, it provides the first 3‐D view of the …
