Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Archaeological Significance
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.
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Talc carbonate vs Argillite 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 Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Argillite. Learn more about Talc carbonate vs Argillite in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Talc carbonate and Argillite, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Argillite include Used for flooring, stair treads, borders and window sills..
More about Talc carbonate and Argillite
Here you can know more about Talc carbonate and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Argillite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Talc carbonate is Soft and that of Argillite is Rough and Dull. Properties of rock is another aspect for Talc carbonate vs Argillite. The hardness of Talc carbonate is 1-2 and that of Argillite is 2-3. The types of Talc carbonate are Sedimentary rock whereas types of Argillite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate is white while that of Argillite is white to grey. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Argillite is 0.87 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 Argillite is heat resistant, impact resistant.
