Definition
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Archaeological Significance
Formation
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
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.

Phyllite 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. Phyllite vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phyllite and Properties of Talc carbonate. Learn more about Phyllite vs Talc carbonate in the next section. The interior uses of Phyllite include Decorative aggregates, 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 Phyllite and Talc carbonate, they have various applications in construction industry. The uses of Phyllite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone and that of Talc carbonate include Source of calcium.
More about Phyllite and Talc carbonate
Here you can know more about Phyllite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phyllite and Talc carbonate consists of mineral content and compound content. The mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon 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 Phyllite vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Phyllite is available in black to grey, light greenish grey colors whereas, Talc carbonate is available in grey, white colors. Appearance of Phyllite is Crinkled or Wavy and that of Talc carbonate is Soft. Properties of rock is another aspect for Phyllite vs Talc carbonate. Hardness of Phyllite and Talc carbonate is 1-2. The types of Phyllite are Phyllite 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 Phyllite and Talc carbonate is white. The specific heat capacity of Phyllite is 0.79 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.Phyllite is heat resistant, pressure resistant, water resistant whereas Talc carbonate is heat resistant, wear resistant.
