1. A fine-grained metamorphic rock formed by the mechanical deformation and crushing of rock during intense shearing, typically found along fault zones.
Usage: geology; technical

Examples

• Geologists identified mylonite samples along the fault line where two tectonic plates had collided.
• The mylonite showed evidence of intense ductile deformation under high pressure.
• Mylonite formations are commonly studied to understand the history of fault movement.
• The rock outcrop displayed the characteristic banded texture of mylonite.
• Researchers collected mylonite specimens to analyze the conditions of the ancient shear zone.
