Definition

A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.

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

Formation

Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

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