5 Formation

5.1 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.

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Anorthosite vs Lignite 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 Lignite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Lignite information and Anorthosite vs Lignite characteristics in the upcoming sections.

Anorthosite vs Lignite 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 Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Lignite. Learn more about Anorthosite vs Lignite in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Anorthosite and Lignite, 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 Lignite include For road aggregate, Steel production.

More about Anorthosite and Lignite

Here you can know more about Anorthosite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Lignite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Lignite, 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, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Anorthosite vs Lignite. The hardness of Anorthosite is 5-6 and that of Lignite is 1. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite is white while that of Lignite is black. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Lignite 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Lignite is heat resistant.
