Fluid‐Mantle Interaction Along the Mariana Convergent Margin
Geochemistry, Geophysics, Geosystems, 2023 Active serpentinite mud volcanoes in the forearc region of the Izu‐Bonin‐Mariana system represent an excellent natural laboratory for studying the geochemical processes along convergent plate margins and the associated forearc. During IODP Expedition 366,

Frontiers in Microbiology, 2023 The demonstration by Ivan Barnes et al. that the serpentinization of fresh Alpine-type ultramafic rocks results in the exhalation of hot alkaline fluids is foundational to the submarine alkaline vent theory (AVT) for life’s emergence to its ‘improbable ...

Green Processing and Synthesis, 2023 Much effort was taken to elucidate how organic precursors appeared in early Earth, and attention was paid to two impact experiments: hypervelocity impacts by a propellant gun which simulated meteorite collides to Earth forming fatty acids and amino acids

Serpentinization-Associated Mineral Catalysis of the Protometabolic Formose System
Life, 2023 The formose reaction is a plausible prebiotic chemistry, famed for its production of sugars. In this work, we demonstrate that the Cannizzaro process is the dominant process in the formose reaction under many different conditions, thus necessitating a ...

Constraints on Bend‐Faulting and Mantle Hydration at the Marianas Trench From Seismic Anisotropy
Geophysical Research Letters, 2023 Subduction zones are a key link between the surface water cycle and the solid Earth, as the incoming plate carries pore water and hydrous minerals into the subsurface.

Olivine versus peridotite during serpentinization: Gas formation
, 2015 The dependence of starting materials and their initial grain sizes on the formation of gases (H-2, CH4, C2H6 and C3H8) during serpentinization was investigated by conducting hydrothermal experiments at 311A degrees C and 3 kbar on olivine and peridotite ...

Giant serpentine aneurysms [PDF]
Neurosurgical Focus, 2009 Segal and McLaurin first described giant serpentine aneurysms, based on their distinct angiographic features, in 1977. These lesions are ≥ 25 mm, partially thrombosed aneurysms with a patent, serpiginous vascular channel that courses through the aneurysm.

Giant serpentine aneurysm [PDF]
BMJ Case Reports, 2016 A 34-year-old man with a history of seizures presented after a generalised seizure. An MRI of the brain and MR angiogram of the brain (figure 1) were performed, demonstrating a partially thrombosed, giant intracranial aneurysm involving the left anterior cerebral artery (ACA).
