Fault Elements and Structural Reactivation
... Fault gouge is the name given to the rock “flour” which results from the grinding up of rock along the fault plane. It is unconsolidated with a very small grain size. Fault gouge has no cohesion, it is normally an unconsolidated rock type, unless cementation took place at a later stage. Fault gouge ...

Stress and Faulting Lab
... Background - Faults When enough stress builds up in rock, the rock breaks, creating a fault. These breaks are called faults. Most faults occur along plate boundaries, where the forces of plate motion push or pull the crust so much that the crust breaks. There are three main types of faults: normal f ...
