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.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

More about Icelandite and Sandstone
Here you can know more about Icelandite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Sandstone 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 Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Icelandite vs Sandstone, 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, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Icelandite is Dull and Soft and that of Sandstone is Rough. Properties of rock is another aspect for Icelandite vs Sandstone. The hardness of Icelandite is 7 and that of Sandstone is 6-7. The types of Icelandite are Not Available whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Icelandite and Sandstone is white. The specific heat capacity of Icelandite is 2.39 kJ/Kg K and that of Sandstone 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.Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
