Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

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

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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