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.
Hornblendite 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 Hornblendite
Here you can know more about Talc carbonate and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Hornblendite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Hornblendite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Hornblendite is available in black, brown, green, grey colors. Appearance of Talc carbonate is Soft and that of Hornblendite is Foliated. Properties of rock is another aspect for Talc carbonate vs Hornblendite. The hardness of Talc carbonate is 1-2 and that of Hornblendite is 6-7. The types of Talc carbonate are Sedimentary rock whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. 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 Hornblendite is white to grey. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Hornblendite is 0.84 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 Hornblendite is heat resistant, pressure resistant, wear resistant.
