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 …

This paper reviews the occurrence and significance of talc-and amphibole-rich fault rocks
developed in mafic-ultramafic sequences and evaluates their role in deformation and …

Oceanic core complexes are the uplifted footwalls of very-large-offset low-angle normal
faults that exhume lower crust and mantle rocks onto the seafloor at slow-spreading ridges …

Normal faults are ubiquitous on mid-ocean ridges and are expected to develop increasing
offset with reduced spreading rate as the proportion of tectonic extension increases …

Small amounts of felsic, evolved plutonic rocks, often called oceanic plagiogranites, always
occur as veins or small stocks within the gabbroic section of the oceanic crust. Four major …

Magma-poor rifted margins consistently show extreme crustal thinning accompanied by
normal faulting, the serpentinization of the mantle beneath crust thinned to less than 8±2 km …

Deformed rocks sampled from a corrugated detachment fault surface near the Mid‐Atlantic
Ridge (15° 45′ N) constrain the conditions of deformation and strain localization. Samples …

The Atlantis Massif (Mid‐Atlantic Ridge, 30° N) is an example of an oceanic core complex
(OCC) exposed by a major fault system. Our integrated field and analytical study of mafic …

We mapped the Kane megamullion, an oceanic core complex on the west flank of the Mid‐
Atlantic Ridge exposing the plutonic foundation of a∼ 50 km long, second‐order ridge …

The oceanic core complex comprising Atlantis Massif was formed within the past 1.5–2 Myr
at the intersection of the Mid-Atlantic Ridge, 30° N, and the Atlantis Transform Fault. The …
