In this process, as deeply buried fault zones are gradually brought to the surface over geological time, the reduction in temperature and confining pressure creates brittle phenomena, such as mesoscale fracturing and microscale cataclasis, which are further altered by fluid movement in the FGWZ.
The mineralization is located at the contact of two regional structural trends where faulting and deformation have produced intense cataclasis and brecciation.
Close to the contact, the fabric in micaceous rocks typically shows the development of a new crenulation cleavage overprinting the generally planar foliation, and more quartz-rich rocks display moderate to strong cataclasis with undulose extinction and bent mica grains (Fig.
The mineralization appears to be located at the intersection of two regional structural trends where deformation has produced intense cataclasis and brecciation.
