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.
Theralite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Talc carbonate and Theralite
Here you can know more about Talc carbonate and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Theralite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Theralite is available in dark grey to black colors. Appearance of Talc carbonate is Soft and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Talc carbonate vs Theralite. The hardness of Talc carbonate is 1-2 and that of Theralite is 7. The types of Talc carbonate are Sedimentary rock whereas types of Theralite are Teschenite and Essexite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Theralite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Theralite is 0.74 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 Theralite is impact resistant, pressure resistant, wear resistant.
