Anorthosite vs Coal

Anorthosite vs Coal 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 Coal Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Coal information and Anorthosite vs Coal characteristics in the upcoming sections.

Anorthosite vs Coal 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 Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Coal. Learn more about Anorthosite vs Coal in the next section.

Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Coal 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 Coal is Veined or Pebbled. Properties of rock is another aspect for Anorthosite vs Coal. The hardness of Anorthosite is 5-6 and that of Coal is 1-1.5. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. 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 Coal is black. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Coal 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 Coal is heat resistant.
