1 Definition

1.1 Definition

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

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

5 Formation

5.1 Formation

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
