5 Formation

5.1 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.

Icelandite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Skarn and Icelandite

Here you can know more about Skarn and Icelandite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Icelandite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Icelandite, 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, Icelandite is available in bluish - grey, grey, pink, yellow colors. Appearance of Skarn is Dull and that of Icelandite is Dull and Soft. Properties of rock is another aspect for Skarn vs Icelandite. The hardness of Skarn is 6.5 and that of Icelandite is 7. The types of Skarn are Endoskarns whereas types of Icelandite 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 Icelandite is white. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Icelandite is 2.39 kJ/Kg K.
