Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock.

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.

Mylonite is a foliated metamorphic rock that is composed of intensely flattened minerals in a fine-grained streaked matrix. Mylonites form deep in the crust where temperature and pressure are high enough for the rocks to deform plastically (ductile deformation).

Mylonite: a mylonite is a foliated and usually lineated rock that shows evidence for strong ductile deformation and normally contains rounded porphyroclasts and lithic fragments of similar composition to minerals in the matrix.

A cohesive fault-rock which is characterised by tectonic reduction of grain size and recrystallisation in shear zones, and commonly contains lensoidal to rounded porphyroclasts and lithic fragments of similar composition to minerals in the matrix.

Mylonites are the products of extreme cataclastic deformation. They are extremely fine-grained, but mineral fragments of the parent rock can be seen under the microscope. Most mylonites are laminated, the layers formed by different grain sizes of deformed material.

The meaning of MYLONITE is a siliceous schist geologically produced by intense crushing of rocks.

Mylonite is a structural term that refers only to the fabric of the rock and does not give information on the mineral composition. Present day use for mylonite refers to rocks dominantly deformed by ductile flow.

Mylonitic rocks are a type of clastic rock (a rock formed by the breaking or crushing of rock fragments or mineral grains), and they include protomylonites, mylonites, and blastomylonites (Fig. 1) (Higgins, 1971).

Mylonite, a fascinating metamorphic rock, stands as a testament to the geological forces that shape our planet. In this comprehensive article, we delve into the intricacies of mylonite, exploring its formation, classification, and unique characteristics.

Nov 11, 2019 · Mylonites form in ductile shear zones and are a type of tectonite subject to fine granulation with a marked alignment that is created by plastic deformation, under which crystal dislocation and dynamic recrystallization of the same structure have taken place.

Mylonites are rocks that have undergone modification of original textures by predominantly plastic flow due to dynamic recystallization. The formation of mylonites occur at depth, below brittle faults, in continental and oceanic crust.

In this contribution, we use a quartz-rich mid-crustal mylonite as a natural laboratory to investigate the coupled processes of dynamic re-crystallization, grain-size reduction, and the evolution of CPO.

Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism.

There are various physical properties of Mylonite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Mylonite rock are vital in determining its Mylonite Texture and Mylonite Uses .

A compact, chertlike rock without cleavage, but with a streaky or banded structure, produced by the extreme granulation and shearing of rocks that have been pulverized and rolled during overthrusting or intense dynamic metamorphism. Mylonite may also be described as a microbreccia with flow texture.

Relationship of uranium deposits to regional albititisation. (A) typical mylonite ore; (B) hydrothermal breccia ore with zircon-U matrix; (C) Early albitite fragments in riebeckite schist with later calcite veins; (D) An example similar to (C) with more intense carbonate veining. Ab–albite, Zr–zircon, Rb–riebeckite, cc–calcite.

Aug 10, 2011 · In mylonites, diffusion profiles combined with geothermometry and grain size analysis indicate a mylonitic deformation temperature of 800–900°C possibly followed by diffusion.

May 1, 2018 · Quartz of metamorphic rocks from the Kaoko belt (Namibia) representing metamorphic zones from greenshist to granulite facies were investigated by cathodoluminescence (CL) microscopy and spectroscopy to characterize their CL properties.

Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of …
