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.

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

More about Anorthosite and Anthracite

Here you can know more about Anorthosite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Anthracite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Anthracite, 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, Anthracite 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 Anthracite is Veined or Pebbled. Properties of rock is another aspect for Anorthosite vs Anthracite. The hardness of Anorthosite is 5-6 and that of Anthracite is 1-1.5. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Anthracite are Semi-anthracite and Meta-anthracite. 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 Anthracite is black. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
