Formation

Formation
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.   
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 Gossan and Icelandite

Here you can know more about Gossan and Icelandite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gossan and Icelandite consists of mineral content and compound content. The mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon 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 Gossan vs Icelandite, the texture, color and appearance plays an important role in determining the type of rock. Gossan is available in brown, brown- black, gold, green, rust colors whereas, Icelandite is available in bluish - grey, grey, pink, yellow colors. Appearance of Gossan is Dull and Banded and that of Icelandite is Dull and Soft. Properties of rock is another aspect for Gossan vs Icelandite. The hardness of Gossan is 4-5 and that of Icelandite is 7. The types of Gossan are Translocated gossan and Leakage gossan 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 Gossan is white to grey while that of Icelandite is white. The specific heat capacity of Gossan is 0.24 kJ/Kg K and that of Icelandite is 2.39 kJ/Kg K.
