A region, narrow in comparison with its length, within which rocks have undergone intense deformation.
fault zone, often associated with fluid movement and mineralisation
an originally planar zone of rock that has been deformed or fractured by shearing motions. Shear zones often act as zones of fluid flow and therefore have associated hydrothermal alteration or mineralization.
A tabular zone of rock that has been crushed by many parallel fractures, typical of a fault zone, due to shear strain.
an area that has undergone intense deformation due to motion along a fault deep in the Earth's crust
area where rocks have moved in earthquake related type activity and broken up the rock
a tabular zone of rock which has been crushed and brecciated by parallel fractures due to "shearing" along a fault or zone of weakness. These can be mineralized with ore-forming solutions
A fault in which movement has occurred ductilely.
A planar zone of weakness, similar to a fault, but consisting of several parallel displacement zones, usually over a greater width than a single fault.
A zone in which shearing has occurred on a large scale.
