Rhyolite is a fine-grained igneous rock which is rich in silica
From German Rhyolit, from Greek rhuax lava stream + lithos stone
Coarse Grained Rock, Opaque Rock
Aphanitic, Glassy, Porphyritic

Gemstone, Laboratory bench tops, Jewelry
Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.
Acidic in nature, Available in lots of colors
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism
From Greek mulōn mill + -ite

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