Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Pyrolite and Conglomerate Properties
Know all about Pyrolite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Pyrolite is Phaneritic whereas that of Conglomerate is Clastic. Pyrolite appears Rough and Shiny and Conglomerate appears Shiny and Rounded. The luster of Pyrolite is shiny while that of Conglomerate is dull. Pyrolite is available in dark greenish - grey colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Conglomerate are cemetery markers, in aquifers, tombstones.
