rock type found in fault zones

Compact rock with streaky or banded structure, found in fault zones, and produced by extreme crushing and shearing of rocks during movement of a fault. It is particularly well developed along the Lake Char - Honey Hill fault zones of the Eastern Uplands.

A fine-grained metamorphic rock formed by extreme crushing and pulverizing along a fault zone.

A compact, chertlike rock without cleavage, but with a banded appearance produced by extreme shearing and pulverizing during metamorphism.

fine-grained rock, with a more or less ribbony texture, deriving from intense crushing of country rocks inside deep-sited faults or overthrusts.

Mylonite is a fine-grained, compact rock without cleavage or crystals. It is classified as a metamorphic rock and has a flow texture. Mylonites can have many different mineralogical compositions, it is a classification on the appearance of the rock.
