Topography [18-20], buoyancy forces [21, 22], and groundwater recharge [19], inducing both a hydraulic gradient and thermal disturbance, exert a significant role on hydrothermal circulation. Petrophysical and thermal properties, especially permeability [23], play a critical role in the establishment of a fluid circulation pattern and thus in the building of possible thermal anomalies [11, 24].
Numerical Models of the Tet Hydrothermal Circulations
These dynamic Structures occur in seafloor-spreading areas along the mid-ocean ridges where the proximity of the underlying magma drives an associated hydrothermal circulation. (See Oceanus bank issues including Summer 1979, Winter 1988/89, and Winter 1991/92 for descriptions and discussions of this phenomenon.) While hydrothermal vents are better understood than they were a decade ago, further observations are required to answer many basic questions.
Surrounding this volume, however, where hydrothermal circulation has cooled the crust to a brittle state, extensional faults penetrate to depths of 5 to 6 kilometers.
