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.

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).

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.

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.

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.

2025年3月23日 · Mylonite, a fascinating rock, tells stories of Earth's dynamic processes. Formed under intense pressure and heat, it showcases the power of tectonic forces. Found in fault zones, this rock is a testament to the planet's ever-changing nature.

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.

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).

2019年11月11日 · 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.

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.
