Suevite and Mylonite
Definition
Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite 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

Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

All about Suevite and Mylonite Properties
Know all about Suevite and Mylonite properties here. All properties of rocks are important as they define the type of rock and its application. Suevite and Mylonite belong to Metamorphic Rocks.Texture of Suevite is Earthy whereas that of Mylonite is Foliated. Suevite appears Banded and Mylonite appears Dull, Banded and Foilated. The luster of Suevite is earthy while that of Mylonite is shiny. Suevite is available in black, brown, colourless, green, grey, pink colors whereas Mylonite is available in black to grey colors. The commercial uses of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo) and that of Mylonite are creating artwork, gemstone, jewelry.
