Definition

Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

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

Sovites are formed due to low degrees of partial melting of rocks.

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