Definition
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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.

Skarn 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. Skarn vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Talc carbonate. Learn more about Skarn vs Talc carbonate in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Skarn and Talc carbonate, they have various applications in construction industry. The uses of Skarn in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Gold and silver production, Manufacture of magnesium and dolomite refractories and that of Talc carbonate include Source of calcium.
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, colourless, green, grey, white colors whereas, Talc carbonate is available in colourless, 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 Not Available. 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.
