Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
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.

Mudstone 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. Mudstone vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Talc carbonate. Learn more about Mudstone vs Talc carbonate in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mudstone and Talc carbonate, they have various applications in construction industry. The uses of Mudstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Talc carbonate include Source of calcium.
More about Mudstone and Talc carbonate
Here you can know more about Mudstone and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Talc carbonate consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Mudstone is Rough and Dull and that of Talc carbonate is Soft. Properties of rock is another aspect for Mudstone vs Talc carbonate. The hardness of Mudstone is 2-3 and that of Talc carbonate is 1-2. The types of Mudstone are Marl, Shale and Argillite 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 Mudstone and Talc carbonate is white. The specific heat capacity of Mudstone is 0.39 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.Mudstone is heat resistant, impact resistant whereas Talc carbonate is heat resistant, wear resistant.
