Magma plumbing systems exert strong controls on the formation and evolution of the
oceanic crust during crust accretion. However, plumbing system dynamics based largely on …

Abstract The Doldrums Megatransform System (~ 7–8° N, Mid-Atlantic Ridge) shows a
complex architecture including four intra-transform ridge segments bounded by five active …

Magma migration and differentiation processes are key to understanding the development
and evolution of oceanic magma reservoirs. To provide new quantitative geochemical …

Abstract The Atlantis Bank Oceanic Batholith is a 660 km2 gabbro massif representing the
plutonic foundation of a major ridge magmatic center. It was continuously accreted …

The exposure of gabbroic sequences at Oceanic Core Complexes (OCC) along ultraslow-to
slow-spreading ridges permits the study of the processes forming the lower oceanic crust …

Mid-ocean ridge magma reservoirs are mush-dominated systems, where reactive porous
flow is a dominant post-cumulus process. However, the length scale of this process is poorly …

Brown amphibole is a minor but common mineral component in lower oceanic crust. It is
generally interpreted as products of migrating SiO2 and H2O-rich fluids or melts, which can …

Carbonatites, carbon-rich magmatic rocks, are thought to form by low-degree partial melting
of a relatively carbon-poor mantle followed by protracted differentiation and immiscibility …

Reactive porous or focused melt flows are common in crystal mushes of mid-ocean ridge
magma reservoirs. Although they exert significant control on mid-ocean ridge magmatic …

Trace element and isotopic compositions of exhumed high-pressure (P) mafic rocks are an
important archive to investigate chemical processes in subduction zones. Here we report the …
