Archaeological Significance
Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
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.

Granulite 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. Granulite vs Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Talc carbonate. Learn more about Granulite vs Talc carbonate in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Granulite and Talc carbonate, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Talc carbonate include Source of calcium.
More about Granulite and Talc carbonate
Here you can know more about Granulite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Talc carbonate consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz 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 Granulite vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Talc carbonate is available in grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Talc carbonate is Soft. Properties of rock is another aspect for Granulite vs Talc carbonate. The hardness of Granulite is 6-7 and that of Talc carbonate is 1-2. The types of Granulite are Metamorphic rock 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 Granulite and Talc carbonate is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
