Mudstone vs Anorthosite


Definition

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

Formation
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 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 vs Mudstone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Anorthosite and Mudstone Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Anorthosite vs Mudstone information and Anorthosite vs Mudstone characteristics in the upcoming sections.

Anorthosite vs Mudstone 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. Anorthosite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Mudstone. Learn more about Anorthosite vs Mudstone in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Anorthosite and Mudstone, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Anorthosite and Mudstone

Here you can know more about Anorthosite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Mudstone consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Anorthosite vs Mudstone. The hardness of Anorthosite is 5-6 and that of Mudstone is 2-3. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Mudstone is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
