Shear zone definition

Shear zone means a zone in which rocks have been deformed by lateral movement along parallel planes
Shear zone means a zone in which crushed rock has been produced by the action of a shearing stress as on a fault. This setting is often favourable for the occurrence of gold mineralisation.
Shear zone means a zone in which rocks have been deformed by lateral movement along parallel planes “Quartz Vein” means a fracture which has been filled by quartz and other minerals which have crystallised from mineralised fluids
