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

Features
Clasts are smooth to touch, Is one of the oldest rock, Matrix variable
Constitutes upper part of the Earth's mantle, Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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.

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