Deep high-temperature hydrothermal circulation in a detachment faulting system on the ultra-slow spreading ridge [PDF]
Nature Communications, 2020 Magmatic and tectonic activity at mid-oceanic ridges can give detailed insights into high-temperature hydrothermal circulation of fluids. The authors here present geochemical and geophysical datasets that suggest a hydrothermal system penetrating the ...

Synergistic Hydrothermal Treatment of Incineration Fly Ash and Sewage Sludge: Effect of Hydrothermal Solution Circulation [PDF]
ACS OmegaIn our previous study, we demonstrated that the hydrothermal process is a feasible method for the synergistic treatment of incineration fly ash and sewage sludge. However, the hydrothermal solution inevitably produced during this process presents a challenging problem.

Sustainability and dynamics of outcrop-to-outcrop hydrothermal circulation [PDF]
Nature Communications, 2015 Most seafloor hydrothermal circulation occurs far from the magmatic influence of mid-ocean ridges, driving large flows of water, heat and solutes through volcanic rock outcrops on ridge flanks.

Magnetic imaging of subseafloor hydrothermal fluid circulation pathways [PDF]
Science Advances, 2020 Magnetic studies of the seafloor have produced the first empirical model of a hydrothermal upflow zone. Hydrothermal fluid circulation beneath the seafloor is an important process for chemical and heat transfer between the solid Earth and overlying ...

Core cracking and hydrothermal circulation can profoundly affect Ceres' geophysical evolution [PDF]
, 2015 Observations and models of Ceres suggest that its evolution was shaped by interactions between liquid water and silicate rock. Hydrothermal processes in a heated core require both fractured rock and liquid.

THM modeling of hydrothermal circulation at Rittershoffen geothermal site, France [PDF]
Geothermal Energy, 2018 Background The Rittershoffen deep geothermal project located 6 km east from Soultz-sous-Forts EGS site (France) includes a doublet GRT-1 and GRT-2 to exploit the geothermal resource at the sediments–granite transition where higher temperatures than those

Hydrothermal circulation cools continental crust under exhumation
Earth and Planetary Science Letters, 2019 Abstract The formation of continental crust in magmatic arcs involves cooling of hot magmas to a relatively colder crust enhanced by exhumation and hydrothermal circulation in the upper crust. To quantify the influence of these processes on the thermal and rheological states of the crust, we developed a one-dimensional thermal evolution model, which ...

Heat Flow Evidence for Hydrothermal Circulation in Oceanic Crust Offshore Grays Harbor, Washington
Geochemistry, Geophysics, Geosystems, 2020 We report 30 new conductive heat flow measurements collected on the Juan de Fuca plate, offshore of Grays Harbor, Washington, just seaward of the deformation front. The data were collected along Cascadia Open‐Access Seismic Transect Lines 4 and 5.
