Definition
Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

Formation
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.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Icelandite vs Basaltic Trachyandesite 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. Icelandite vs Basaltic Trachyandesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Icelandite and Properties of Basaltic Trachyandesite. Learn more about Icelandite vs Basaltic Trachyandesite in the next section. The interior uses of Icelandite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Basaltic Trachyandesite include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Icelandite and Basaltic Trachyandesite, they have various applications in construction industry. The uses of Icelandite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Basaltic Trachyandesite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Icelandite and Basaltic Trachyandesite
Here you can know more about Icelandite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Icelandite vs Basaltic Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Icelandite is Dull and Soft and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Icelandite vs Basaltic Trachyandesite. The hardness of Icelandite is 7 and that of Basaltic Trachyandesite is 6. The types of Icelandite are Not Available whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Icelandite is white while that of Basaltic Trachyandesite is white to grey. The specific heat capacity of Icelandite is 2.39 kJ/Kg K and that of Basaltic Trachyandesite is 0.84 kJ/Kg K.
