Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Pyrolite 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.
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.

All about Pyrolite and Suevite Properties
Know all about Pyrolite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Pyrolite is Phaneritic whereas that of Suevite is Earthy. Pyrolite appears Rough and Shiny and Suevite appears Banded. The luster of Pyrolite is shiny while that of Suevite is earthy. Pyrolite is available in dark greenish - grey colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
