We compare fracture closure and related flow change during isotropic loading of two fractures which have been subject to various amounts of paleo-reactive flow. The two tested fractures are described as (i) a small-aperture fracture (0.1 mm) with negligible geochemical alterations of the fracture surface and (ii) a large-aperture fracture (0.53 mm) where precipitates are observed on the fracture surface.</p>NGI Geomechanical laboratory, Oslo38.93792110.13892The Research Council of Norway244049
