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.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

Talc carbonate vs Wackestone 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 Wackestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Wackestone. Learn more about Talc carbonate vs Wackestone in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Talc carbonate and Wackestone, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Wackestone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Talc carbonate and Wackestone
Here you can know more about Talc carbonate and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Wackestone consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Wackestone 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 Wackestone, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Talc carbonate is Soft and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Talc carbonate vs Wackestone. The hardness of Talc carbonate is 1-2 and that of Wackestone is 2-3. The types of Talc carbonate are Sedimentary rock whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Wackestone is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Wackestone is 0.39 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 Wackestone is heat resistant, impact resistant.
