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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Icelandite vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Icelandite and Properties of Talc carbonate. Learn more about Icelandite vs Talc carbonate in the next section. The interior uses of Icelandite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Icelandite and Talc carbonate, they have various applications in construction industry. The uses of Icelandite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Talc carbonate include Source of calcium.
More about Icelandite and Talc carbonate
Here you can know more about Icelandite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Talc carbonate 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 Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Igneous Rocks. When we have to compare Icelandite vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Icelandite is Dull and Soft and that of Talc carbonate is Soft. Properties of rock is another aspect for Icelandite vs Talc carbonate. The hardness of Icelandite is 7 and that of Talc carbonate is 1-2. The types of Icelandite are Not Available whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Icelandite and Talc carbonate is white. The specific heat capacity of Icelandite is 2.39 kJ/Kg K and that of Talc carbonate 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 Talc carbonate is heat resistant, wear resistant.
