Fault breccia

Fault breccia, or tectonic breccia, is a breccia (a rock type consisting of angular clasts) that was formed by tectonic forces. Fault breccia is a tectonite formed by localized zone of brittle deformation (a fault zone) in a rock. Brecciation in fault zones influences fault zone hydrogeology in its interaction with groundwater and petroleum deposits.
