Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Sedimentary rock
Features
Available in Lots of Colors and Patterns, Smooth to touch, Very fine grained rock
Easily splits into thin plates, Generally rough to touch, Host Rock for Lead
Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of 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.

Claystone 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. Claystone vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Talc carbonate. Learn more about Claystone vs Talc carbonate in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Claystone and Talc carbonate, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, 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 Claystone and Talc carbonate
Here you can know more about Claystone and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Talc carbonate consists of mineral content and compound content. The mineral content of Claystone 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 Claystone vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Talc carbonate is available in grey, white colors. Appearance of Claystone is Rough and Dull and that of Talc carbonate is Soft. Properties of rock is another aspect for Claystone vs Talc carbonate. The hardness of Claystone is 3.5-4 and that of Talc carbonate is 1-2. The types of Claystone are Claystone 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 Claystone and Talc carbonate is white. The specific heat capacity of Claystone 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.Claystone is heat resistant, impact resistant whereas Talc carbonate is heat resistant, wear resistant.
