Cataclasite - Wikipedia
Cataclasite is a cohesive granular fault rock. [1] Comminution , also known as cataclasis, is an important process in forming cataclasites. [ 2 ] They fall into the category of cataclastic rocks which are formed through faulting or fracturing in the upper crust . [ 3 ]
Cataclastic rock - Wikipedia
Cataclasis involves the granulation, crushing, or milling of the original rock, then rigid-body rotation and translation of mineral grains or aggregates before lithification. Cataclastic rocks are associated with fault zones and impact event breccias.
Cataclasite - ALEX STREKEISEN
Cataclasite: Cataclasite: Fault-related rock that maintained primary cohesion during deformation, with matrix comprising greater than 10 % of rock mass; matrix is fine-grained material formed through grain size reduction. Cataclasites are subdivided into those that have 10-50% matrix (protocataclasite), 50-90% matrix (cataclasite) and > 90% ...

2024年6月1日 · The cataclasite exhibits a distinct red-brown staining from the presence of iron oxide. It localized systematically near strength contrasts within the layered fault rocks of the BCD footwall.
Fault Rocks, Deformation & Metamorphism - Britannica
Cataclastite, any rock produced by dynamic metamorphism during which faulting, granulation, and flowage may occur in previously crystalline parent rocks. When stress exceeds breaking strength, a rock yields by rupture. The rock may break …

2018年10月24日 · Cataclasite and melt rock are found in tension fractures (Fig. 5h), which, to some extent, formed from shear faults. Brittle–ductile band structures displace zones of cataclasite, crenulated ...
Cataclastic rocks - SpringerLink
Cataclasis is the granulation, crushing, or milling of a coherent rock mass to produce a more finely grained material called a cataclastic rock. Cataclastic deformation entails both the fracture and subsequent rigid-body rotation of mineral grains or aggregates.
Cataclasites - SpringerLink
2009年1月1日 · The cataclasites presented in this chapter are all cohesive fault rocks that show evidence of brittle fracturing although other processes such as grain boundary sliding and pressure solution may have played a role in their formation as well.
Cataclastic rocks - SpringerLink
Cataclastic rocks are produced by dynamic ( cataclastic , dislocation ) metamorphism in discrete zones of differential stress and movement (process is termed cataclasis from Greek kata, down and klasis, a breaking), e.g., faults, thrust zones, and shear zones.
