Modeling Permeability Changes Caused by Hydrothermal Circulation

Natural Resources Research, 2000
A new model for simulating porosity and permeability changes caused by sedimentary reservoirsdiagenesis is presented. Permeability is computed from changes in the mineral volume fractionsresulting from precipitation and dissolution of the rock-forming mineral as fluid flows throughvariable salinity and temperature fields. Its evolution is controlled by

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 ...

Tracing fluid–rock reaction and hydrothermal circulation at the Saldanha hydrothermal field

Chemical Geology, 2010
The Saldanha hydrothermal field is positioned on the top of a seamount located in a non-transform offset (NTO5) on the Mid-Atlantic Ridge (MAR). This hydrothermal system was first described as a low-temperature diffuse field, driven by peridotite–seawater reactions following the detection of high concentrations of CH4 and H2 in the water column, and ...

Numerical models for hydrothermal circulation in the oceanic crust

Journal of Geophysical Research, 1976
Two-dimensional numerical calculations of hydrothermal circulation in permeable oceanic crust have been carried out. The effects of Rayleigh number, impermeable and permeable upper boundaries, and permeability variations with depth have been investigated. Flow and temperature fields as well as surface heat flux distributions are presented.

Hydrothermal Circulation and Geochemical Flux at Mid-Ocean Ridges

The Journal of Geology, 1976
The flow rate of sea water through sub-sea-floor hydrothermal systems at mid-ocean ridges has been estimated at $$1.3-9 \times 10^{17} g/yr$$ by consideration of the rate at which circulating fluid must advect heat out of the spreading plates into the oceans.

Hydrothermal circulation in subducting crust reduces subduction zone temperatures

Geology, 2008
Most thermal models of subduction zones assume no advection of heat by fluid flow because slow flow through underthrusting sediment, the decollement, and wedge likely transports only a minor amount of heat. We model coupled fluid and heat transport in a subduction zone and show that hydrothermal circulation in subducting basaltic basement rocks can ...

Faulting-hydrothermal Circulation Relationships Constrained by Thermogene Travertine Dating, Albegna Valley, Italy

Proceedings, 2014
This work presents preliminary geochronological (230Th/234U) and structural data carried out on the travertine deposits and country rock units outcropping in the Albegna Valley, central Apennines, Italy. Travertine, lying in unconformity on top of Neogene-Pleistocene deposits, forms N-S aligned bodies in areas characterized by both fossil and active ...
