Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

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