Formation

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

More about Skarn and Talc carbonate

Here you can know more about Skarn and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Talc carbonate consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, green, grey, white colors whereas, Talc carbonate is available in grey, white colors. Appearance of Skarn is Dull and that of Talc carbonate is Soft. Properties of rock is another aspect for Skarn vs Talc carbonate. The hardness of Skarn is 6.5 and that of Talc carbonate is 1-2. The types of Skarn are Endoskarns whereas types of Talc carbonate are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Skarn is light to dark brown while that of Talc carbonate is white. The specific heat capacity of Skarn is 0.92 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.Skarn is heat resistant whereas Talc carbonate is heat resistant, wear resistant.
