Mantle rock exposures at oceanic core complexes along mid-ocean ridges

J Ciazela, J Koepke, HJB Dick, A Muszynski - Geologos, 2015 - sciendo.com
The mantle is the most voluminous part of the Earth. However, mantle petrologists usually
have to rely on indirect geophysical methods or on material found ex situ. In this review …

Geomorphology of the central Red Sea Rift: Determining spreading processes

N Augustin, FM van der Zwan, CW Devey, M Ligi… - Geomorphology, 2016 - Elsevier
Continental rifting and ocean basin formation is occurring today in the Red Sea, providing a
possible modern analogue for the creation of mid-ocean ridges. Yet many of the seafloor …

780 thousand years of upper‐crustal construction at a melt‐rich segment of the ultraslow spreading Southwest Indian Ridge 50° 28′ E

J Chen, M Cannat, C Tao, D Sauter… - Journal of Geophysical …, 2021 - Wiley Online Library
Melt supply at the ultraslow‐spreading Southwest Indian Ridge (SWIR) has been shown to
vary from nearly amagmatic, leading to ultramafic seafloor, to magmatically robust …

Volcanism in slab tear faults is larger than in island-arcs and back-arcs

L Cocchi, S Passaro, FC Tontini, G Ventura - Nature communications, 2017 - nature.com
Subduction-transform edge propagators are lithospheric tears bounding slabs and back-arc
basins. The volcanism at these edges is enigmatic because it is lacking comprehensive …

Thermal regime of slow and ultraslow spreading ridges controlled by melt supply and modes of emplacement

J Chen, JA Olive, M Cannat - Journal of Geophysical Research …, 2022 - Wiley Online Library
Melt supply at slow‐ultraslow spreading ridges is overall reduced and highly variable.
Magma cooling and crystallization substantially shape the axial thermal regime by providing …
