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

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.
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.

Mudstone vs Peridotite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Mudstone vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Peridotite. Learn more about Mudstone vs Peridotite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mudstone and Peridotite, they have various applications in construction industry. The uses of Mudstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Peridotite include As dimension stone, Cobblestones.
More about Mudstone and Peridotite
Here you can know more about Mudstone and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Peridotite consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Mudstone is Rough and Dull and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Mudstone vs Peridotite. The hardness of Mudstone is 2-3 and that of Peridotite is 5.5-6. The types of Mudstone are Marl, Shale and Argillite whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Peridotite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Peridotite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mudstone is heat resistant, impact resistant whereas Peridotite is heat resistant, pressure resistant, wear resistant.
