Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Harzburgite is a plutonic rock of the peridotite group consisting largely of orthopyroxene and olivine

Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
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.

All about Mudstone and Harzburgite Properties
Know all about Mudstone and Harzburgite properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone belongs to Sedimentary Rocks while Harzburgite belongs to Igneous Rocks.Texture of Mudstone is Clastic whereas that of Harzburgite is Phaneritic. Mudstone appears Rough and Dull and Harzburgite appears Rough and Shiny. The luster of Mudstone is dull while that of Harzburgite is shiny. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Harzburgite is available in dark greenish - grey colors. The commercial uses of Mudstone are creating artwork, pottery and that of Harzburgite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
