Formation
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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Talc carbonate and Andesite
Here you can know more about Talc carbonate and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Andesite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Talc carbonate is Soft and that of Andesite is Dull and Soft. Properties of rock is another aspect for Talc carbonate vs Andesite. The hardness of Talc carbonate is 1-2 and that of Andesite is 7. The types of Talc carbonate are Sedimentary rock whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Andesite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Talc carbonate is heat resistant, wear resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
