Definition
Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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