Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Skarn vs Enderbite 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. Skarn vs Enderbite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Enderbite. Learn more about Skarn vs Enderbite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Enderbite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Skarn and Enderbite, they have various applications in construction industry. The uses of Skarn in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Gold and silver production, Manufacture of magnesium and dolomite refractories and that of Enderbite include As dimension stone.
More about Skarn and Enderbite
Here you can know more about Skarn and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Enderbite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite 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 Metamorphic Rocks. When we have to compare Skarn vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Skarn is Dull and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Skarn vs Enderbite. The hardness of Skarn is 6.5 and that of Enderbite is 6-7. The types of Skarn are Endoskarns 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 Skarn is light to dark brown while that of Enderbite is white. The specific heat capacity of Skarn is 0.92 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.Skarn is heat resistant whereas Enderbite is heat resistant, wear resistant.
