An assessment of field evidence for ‘Byerlee’ friction

WebThe deformational characteristics of two limestones, one gabbro, and one dunite have been investigated as a function of confining pressure. It was found that friction of these rocks and friction of granite and serpentinite studied elsewhere are nearly identical and that the brittle-ductile transition pressure is simply the pressure at which the stress required to form a … Webfirst noted by Byerlee and Summers [1976]. In studies where friction velocity dependence was measured at very short dis- placement (<3 mm), friction of simulated gouge depends posi- tively on the log of slip velocity (dg•/ dlnV > 0, velocity strengthening), a property which precludes instability at all val- ues of k [Tullis, 1988]. suzuki bontó ujpest
