Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
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 Flint and Talc carbonate
Here you can know more about Flint and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Talc carbonate consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Flint is Glassy or Pearly and that of Talc carbonate is Soft. Properties of rock is another aspect for Flint vs Talc carbonate. The hardness of Flint is 7 and that of Talc carbonate is 1-2. The types of Flint are Not Available whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Flint and Talc carbonate is white. The specific heat capacity of Flint is 0.74 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.Flint is heat resistant, impact resistant, pressure resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
