Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
  
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption

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.
  
Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Talc carbonate vs Tuff 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. Talc carbonate vs Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Tuff. Learn more about Talc carbonate vs Tuff in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Talc carbonate and Tuff, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Tuff include Building houses or walls, Construction aggregate.
More about Talc carbonate and Tuff
Here you can know more about Talc carbonate and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Tuff consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in colourless, grey, white colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Talc carbonate is Soft and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Talc carbonate vs Tuff. The hardness of Talc carbonate is 1-2 and that of Tuff is 4-6. The types of Talc carbonate are Not Available whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Tuff is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Tuff is 0.20 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 Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
