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
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase

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.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Mudstone vs Anorthosite 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 Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Anorthosite. Learn more about Mudstone vs Anorthosite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Mudstone and Anorthosite, 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 Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Mudstone and Anorthosite
Here you can know more about Mudstone and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Anorthosite 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 Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Anorthosite, 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, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Mudstone is Rough and Dull and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mudstone vs Anorthosite. The hardness of Mudstone is 2-3 and that of Anorthosite is 5-6. The types of Mudstone are Marl, Shale and Argillite whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Anorthosite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Anorthosite is 0.84 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 Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
