Formation

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.

More about Talc carbonate and Pseudotachylite

Here you can know more about Talc carbonate and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Pseudotachylite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Pseudotachylite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Pseudotachylite is available in black, brown, green, grey, pink, white colors. Appearance of Talc carbonate is Soft and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Talc carbonate vs Pseudotachylite. The hardness of Talc carbonate is 1-2 and that of Pseudotachylite is 7. The types of Talc carbonate are Sedimentary rock whereas types of Pseudotachylite are Cataclastic rock. 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 Pseudotachylite is light to dark brown. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Pseudotachylite 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.Talc carbonate is heat resistant, wear resistant whereas Pseudotachylite is heat resistant.
