Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
  
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Dunite and Enderbite
Here you can know more about Dunite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Enderbite consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Dunite is Rough and Shiny and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Dunite vs Enderbite. The hardness of Dunite is 3.5-4 and that of Enderbite is 6-7. The types of Dunite are Not Available whereas types of Enderbite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Enderbite is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Enderbite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dunite is heat resistant, pressure resistant, wear resistant whereas Enderbite is heat resistant, wear resistant.
