Description:
Fluid overpressures are well known from
hydrocarbon exploration in many sedimentary
basins. They can reach almost
lithostatic values, and may cause
the fracturing of rock. Fracturing allows
the discharge of fluid overpressure, and
fluid flows along a hydraulic gradient towards
a low pressure reservoir. Different
mechanisms may cause the precipitation
from the fluid, such as a fluid pressure drop, a variation of temperature
at the low pressure reservoir, or
a different rock type inducing different
Eh-pH conditions. Such precipitates
in fractures are called veins, which often
display paleo-fluid overpressures in
rocks. In this study, we present some results
from Devonian clastic sedimentary
rocks of the Eifel area. Results are compared
with other sedimentary basins to
highlight some general aspects.
