Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

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