Definition
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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

All about Peridotite and Conglomerate Properties
Know all about Peridotite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Conglomerate is Clastic. Peridotite appears Rough and Shiny and Conglomerate appears Shiny and Rounded. The luster of Peridotite is shiny while that of Conglomerate is dull. Peridotite 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 Peridotite 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.
