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
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

Archaeological Significance
Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Mylonite and Latite Properties
Know all about Mylonite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Mylonite belongs to Metamorphic Rocks while Latite belongs to Igneous Rocks.Texture of Mylonite is Foliated whereas that of Latite is Aphanitic to Porphyritic. Mylonite appears Dull, Banded and Foilated and Latite appears Rough. The luster of Mylonite is shiny while that of Latite is subvitreous to dull. Mylonite is available in black to grey colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Mylonite are creating artwork, gemstone, jewelry and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
