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.   
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Anorthosite vs Claystone 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 Claystone Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. 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 Claystone information and Anorthosite vs Claystone characteristics in the upcoming sections.

Anorthosite vs Claystone 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 Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Claystone. Learn more about Anorthosite vs Claystone in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Anorthosite and Claystone, 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 Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Anorthosite and Claystone

Here you can know more about Anorthosite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Claystone consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Claystone 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 Claystone, 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, Claystone 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 Claystone is Rough and Dull. Properties of rock is another aspect for Anorthosite vs Claystone. The hardness of Anorthosite is 5-6 and that of Claystone is 3.5-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Claystone is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Claystone is 0.92 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 Claystone is heat resistant, impact resistant.
