Image Fault breccia Keystone Thrust Red Rock Canyon NV.jpg thumb right Fault breccia of the Keystone Thrust, Red Rock Canyon National Conservation Area , Nevada. Fault breccia IPAc en icon b r t i or IPAc en b r i Italian for breach , or tectonic breccia , is a breccia a rock geology rock type consisting of angular clast s that was formed by tectonics tectonic forces. Fault breccia is a tectonite formed by localized zone of brittle deformation a fault geology fault zone in a rock. Origin Fault breccias are tectonites formed primarily by tectonic movement along a localized zone of brittle deformation a fault geology fault zone in a rock formation or province. The grinding and milling occurring when the two sides of the fault zone moving along each other results in a material that is made of loose fragments. Because of this fragmentation fault zones are easily infiltrated by groundwater . Secondary minerals such as calcite , epidote , quartz or talc can precipitation chemistry precipitate from the circulating groundwater filling the voids and cementing the rock. However, when the tectonic movement along the fault zone continues the cement itself can be fragmented leading to a new gouge material containing neoformed clasts. Deeper in the Earth s crust geology crust , where temperatures and pressures are higher, the rocks in the fault zone can still brecciate, but they keep their internal cohesion. The resulting type of rock is called a cataclasite . Properties Fault breccia has no cohesion , it is normally an consolidation soil unconsolidated rock type, unless cementation took place at a later stage. Sometimes a distinction is made between fault gouge and fault breccia, the first has a smaller grain size . ref Twiss, R.J. & Moores, E.M., 2000 6th edition Structural Geology , W.H.

As nuclear fuel, uranium carbide can be used either on its own, or mixed with plutonium carbide PuC and Pu sub 2 sub C sub 3 sub . The mixture is also labeled as uranium plutonium carbide PuC U . Uranium carbide is also a popular target material for particle accelerator s. Ammonia synthesis from nitrogen and hydrogen is sometimes accomplished in the presence of uranium carbide acting as a catalyst. ref Hutchings, G.
