== Formation == Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones. There are many different views on the formation of mylonites, but it is generally agreed that crystal-plastic deformation must have occurred, and that fracturing and cataclastic flow are secondary processes in the format...

(from the article `cataclastite`) Mylonites are the products of extreme cataclastic deformation. They are extremely fine-grained, but mineral fragments of the parent rock can be seen ... These are rocks in which the texture is the result of ductile shearing or mechanical shattering of grains. They often show only slight, if any, ... ...

Mylonite is a type of metamorphic rock created when pre-existent rocks are crushed, ground or rolled into a new formation along major fault lines. Mylonite is generated by pressure with very little heat. Mylonite rock is ground to dust and streaked out into bands during its creation.
