Coal vs Picrite

Coal vs Picrite 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 Coal and Picrite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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.

Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Picrite is available in black, brown, green, grey, pink, white, yellow colors. Appearance of Coal is Veined or Pebbled and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Coal vs Picrite. The hardness of Coal is 1-1.5 and that of Picrite is 6.8. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Picrite are Oceanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Picrite is white, greenish white or grey. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Picrite is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Picrite is heat resistant.
