Recycled arc mantle recovered from the Mid-Atlantic Ridge [PDF]
Nature Communications, 2020 Plate tectonics necessitates mantle recycling throughout Earth’s history, yet direct geochemical evidence for mantle reprocessing remains elusive. Here, the authors present evidence of recycled supra-subduction zone mantle wedge peridotite dredged from ...

Microbial iron mats at the Mid-Atlantic Ridge and evidence that Zetaproteobacteria may be restricted to iron-oxidizing marine systems. [PDF]
PLoS ONE, 2015 Chemolithoautotrophic iron-oxidizing bacteria play an essential role in the global iron cycle. Thus far, the majority of marine iron-oxidizing bacteria have been identified as Zetaproteobacteria, a novel class within the phylum Proteobacteria.

Dense cold‐water coral garden of Paragorgia johnsoni suggests the importance of the Mid‐Atlantic Ridge for deep‐sea biodiversity [PDF]
Ecology and Evolution, 2021 Mid‐ocean ridges generate a myriad of physical oceanographic processes that favor the supply of food and nutrients to suspension‐ and filter‐feeding organisms, such as cold‐water corals and deep‐sea sponges.

Occurrence and characterization of tremolite asbestos from the Mid Atlantic Ridge [PDF]
Scientific Reports, 2021 Tremolite is one of the most common amphibole species and, in the fibrous form (i.e., characterized by crystals/particles consisting of fibres with length > 5 µm, width 3), one of the six asbestos minerals.

Detachment tectonics at Mid-Atlantic Ridge 26°N. [PDF]
Sci Rep, 2019 AbstractSpreading processes associated with slow-spreading ridges are a complex interplay of volcanic accretion and tectonic dismemberment of the oceanic crust, resulting in an irregular seafloor morphology made up of blocks created by episodes of intense volcanic activity or tectonic deformation. These blocks undergo highly variable evolution, such as

The production of methane, hydrogen, and organic compounds in ultramafic-hosted hydrothermal vents of the Mid-Atlantic Ridge. [PDF]
Astrobiology, 2015 Both hydrogen and methane are consistently discharged in large quantities in hydrothermal fluids issued from ultramafic-hosted hydrothermal fields discovered along the Mid-Atlantic Ridge. Considering the vast number of these fields discovered or inferred,

Volcanic Geological Sites in UGGp European Geoparks: Special Issue [PDF]
Geoconservation Research, 2023 In this Special Issue, we present 11 of the 15 geoparks that show key aspects of the past and current volcanic development of Europe. The sites include currently active locations along the mid-Atlantic ridge, from the Canary Islands and the Azores in the

Ancient refractory asthenosphere revealed by mantle re-melting at the Arctic Mid Atlantic Ridge
Earth and Planetary Science Letters, 2021 The upper mantle is a heterogeneous mixture of refractory and recycled crustal domains. The recycled portions, more fertile and thus preferentially melted, dominate the composition of the basalts erupted on the surface, whereas the imprint of melting of ...

Nature Communications, 2022 Uniform magmatic crust formed at the Mid-Atlantic Ridge in the equatorial Atlantic Ocean reveals a two-dimensional mantle upwelling facilitated by the large transform faults and the high concentration of volatiles in the primitive melt in the mantle.
