    crushing in the Bner clast size fraction The proportion of clasts, compared to the matrix, is very small in MPt, increases in CPt and is highest in Ct, suggesting that melting of rock/mineral fragments is a dominant process in forming MPt, whereas it is less significant in CPt, and is absent in Ct, which corroborates the microscopic observations

    of localised crushing and melting of the host rock during rapid (≥1.0 m/s) fault slip (McKenzie and Brune 1972; Sibson 1975; Cowan 1999). In the outcrop scale, pseudotachylyte usually occurs as a network of veins, filling the fractures associated with a fault zone. Texturally, pseudotachylyte is composed of numerous fragments (clasts) of the

    Answer: Change into a sedimentary rock! How do you change? 1) You lie deep below the surface of the earth, where there is extreme heat and pressure. 2) A fault (crack in the Earth’s crust) nearby fills with magma, increasing the temperature around you. 3) The heat causes your minerals to change.

  • Size distribution of survivor clasts in pseudotachylyte

    10/20/2020· Size-frequency relationship follows a power law in melting- and crushing-dominated pseudotachylytes. The power law does not hold good for the finest and coarsest size ranges in both types of pseudotachylytes. For cataclasite, a multi-fractal power law relationship exists between the size and cumulative frequency of clasts.

  • Metamorphism Wikipedia

    Cataclasis, crushing and grinding of rocks into angular fragments, occurs in dynamic metamorphic zones, giving cataclastic texture. The textures of dynamic metamorphic zones are dependent on the depth at which they were formed, as the temperature and confining pressure determine the deformation mechanisms which predominate.

    5/10/2019· This does two things: First, the rock grows hard enough to ring or "tink" under the hammer; second, the rock gets a pronounced cleavage direction, so that it breaks along flat planes. Slaty cleavage is not always in the same direction as the original sedimentary bedding planes, thus any fossils originally in the rock are usually erased, but sometimes they survive in smeared or stretched form.
