The Rôle of Faults on Hydrothermal Circulations in the Têt Valley (Eastern Pyrénées)
Proceedings, 2015Hot springs in continental systems often localize near major faults. Faults may act as drains or barrier for hydrothermal circulation, depending on their core zone constitution and permeability, and the fracture density, opening, and connectivity in their damage zone. The interplay between these processes is still unknown and remains to be studied. The

On the fate of sulfate during hydrothermal circulation at mid-ocean ridges
Earth and Planetary Science Letters, 1982Reliable sulfate data are reported for seafloor hydrothermal vents at the Galapagos Rift at 86°W and the East Pacific Rise at 21°N. Making use of sulfate-3He systematics, a loss of sulfate comparable to the river input is estimated. It is argued that the dominant chemical mechanism is reduction by iron, a conclusion based on strontium systematics and ...

Neptunic dikes and their relation to the hydrodynamic circulation of submarine hydrothermal systems
Geology, 1983Neptunic dikes in Lower Jurassic sedimentary rocks of the Tethyan margins consist of internal sediment in cavities and submarine cement. The textures of the infilling sediment indicate downward and lateral movements of seawater beneath what was probably a deep-sea floor.

FlankFlux: an experiment to study the nature of hydrothermal circulation in young oceanic crust
Canadian Journal of Earth Sciences, 1992The sediment-buried eastern flank of the Juan de Fuca Ridge provides a unique environment for studying the thermal nature and geochemical consequences of hydrothermal circulation in young ocean crust. Just 18 km east of the spreading axis, where the sea-floor age is 0.62 Ma, sediments lap onto the ridge flank and create a sharp boundary between ...

Heat-flow and hydrothermal circulation at the ocean–continent transition of the eastern gulf of Aden
Earth and Planetary Science Letters, 2010Abstract In order to investigate the importance of fluid circulation associated with the formation of ocean–continent transitions (OCT), we examine 162 new heat-flow (HF) measurements in the eastern Gulf of Aden, obtained at close locations along eight seismic profiles and with multi-beam bathymetry.

Defining a 3D physical model for the hydrothermal circulation at Campi Flegrei caldera (Italy)
Journal of Volcanology and Geothermal Research, 2013Abstract Our study is aimed to develop a 3D physical model of the Campi Flegrei geothermal system, in order to achieve a more accurate and comprehensive representation of the hydrothermal processes occurring in the caldera. The new model, developed by using the TOUGH2 code simulator, accounts for the caldera rocks' physical properties, bathymetry and

Hydrothermal circulation, anhydrite precipitation, and thermal structure at ridge axes
Journal of Geophysical Research: Solid Earth, 1991The thermal structure of the axial region of ridges spreading at 60 mm yr−1 was studied by comparing observations with numerical thermal models. Data from Deep Sea Drilling Project hole 504B constrain the temperature in the pillows and the upper part of the dike complex. Seismic reflection data constrain the depth to the magma chamber.
