Where is fault breccia found?

Fault breccias exist purely in the elastico-frictional domain with incohesive breccias restricted to the near-surface, between 1-4km depth, while cohesive breccias are found between 10-15km depth (Sibson, 1977).

How is Cataclasite formed?

Cataclasite is a metamorphic rock that is formed by mechanical shear stress during faulting. It is either incohesive or cohesive with poor schistosity. It is usually non-foliated and consists of angular clasts in a finer-grained matrix.

What is fault gouge in geology?

Fault gouge is crushed and ground-up rock produced by friction between the two sides when a fault moves.

How is mylonite formed?

The mylonite is a fine-grained, partially recrystallized metamorphic rock produced by dynamic recrystallization with pronounced foliation as a result of intense shearing during large-scale movements along faults and thrusts.

How is Pseudotachylite formed?

Because pseudotachylite forms through friction-induced melting along a fault surface during a major seismic slip [6,7], the occurrence itself has important implications for understanding paleo-earthquake or faulting activity.

What is mylonite used for?

Uses – as aggregate in the construction and roading industries. New Zealand occurrences – Paparoa Metamorphic Core Complex (northwest coast, South Island), sporadic occurrences along the Alpine Fault, Stewart Island.

What is a normal fault in science?

normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

What is breccia used for?

Names such as “Breccia Oniciata,” “Breccia Pernice,” and “Breccia Damascata” are cut and polished limestones and marbles that reveal a broken, angular pattern. These breccias are used as architectural stones for interior building veneers, tiles, window sills, and other decorative applications.
