Pulsated Global Hydrogen and Methane Flux at Mid‐Ocean Ridges Driven by Pangea Breakup
Geochemistry, Geophysics, Geosystems, 2020 Molecular hydrogen production occurs through the serpentinization of mantle peridotite exhumed at mid‐ocean ridges. Hydrogen is considered essential to sustain microbial life in the subsurface; however, estimates of hydrogen flux through geological time ...

Economic Record, EarlyView.We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Between the Indian Ocean and the Gulf: Ceramics From Ḥattā Oasis in the Emirate of Dubai
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT This study presents the ceramic finds from archaeological investigations conducted in 2024 at two settlements: ‘Islamic Village' and Suhaila 2, one of a number of mountain villages of the Late Islamic period within the Ḥattā Oasis: a high‐altitude exclave in the Emirate of Dubai. The sites are located on the northeastern slopes of Jabal Qallāt

Diffuse Flow On and Around Hydrothermal Vents at Mid-Ocean Ridges [PDF]
Oceanography, 2012 Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor.

The volcanic history and geochemical evolution of the Hveragerði Region, S. W. Iceland. [PDF]
, 1992 The Hveragerði Region is situated at the Hengill Triple junction, SW Iceland, where there are three volcanic systems. The crust in the area is constructed from both fissure (elongate) and lava shield (conical) eruptive units.

Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Partial Melting of Lower Oceanic Crust Gabbro: Constraints From Poikilitic Clinopyroxene Primocrysts
Frontiers in Earth Science, 2018 Successive magma batches underplate, ascend, stall and erupt along spreading ridges, building the oceanic crust. It is therefore important to understand the processes and conditions under which magma differentiates at mid ocean ridges.
