Formation

Formation
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.   
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.

Blue Granite vs Skarn 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 Blue Granite and Skarn Reserves. Blue Granite is an igneous rock and a variety of Larvikite, notable for the presence of thumbnail-sized blue crystals of feldspar. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. 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 Blue Granite vs Skarn information and Blue Granite vs Skarn characteristics in the upcoming sections.

More about Blue Granite and Skarn

Here you can know more about Blue Granite and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blue Granite and Skarn consists of mineral content and compound content. The mineral content of Blue Granite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite. You can also check out the list of all Igneous Rocks. When we have to compare Blue Granite vs Skarn, the texture, color and appearance plays an important role in determining the type of rock. Blue Granite is available in black, brown, light to dark grey, white colors whereas, Skarn is available in black, brown, green, grey, white colors. Appearance of Blue Granite is Shiny and that of Skarn is Dull. Properties of rock is another aspect for Blue Granite vs Skarn. The hardness of Blue Granite is 6-7 and that of Skarn is 6.5. The types of Blue Granite are Granite whereas types of Skarn are Endoskarns. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Blue Granite is white while that of Skarn is light to dark brown. The specific heat capacity of Blue Granite is 0.79 kJ/Kg K and that of Skarn is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Blue Granite is heat resistant, impact resistant, pressure resistant whereas Skarn is heat resistant.
