WebApr 11, 2024 · Low-angle normal faults (LANFs) are poorly understood, as their slip at <30° dips appears inconsistent with Byerlee friction and Andersonian stresses. Rider blocks are fault slices formed when the uppermost part of a LANF is abandoned in favor of a new, steeper fault. Mohr-Coulomb modeling of rider blocks can constrain fault frictional and ... 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].
