Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Talc carbonate
Here you can know more about Charnockite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Talc carbonate consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Charnockite is Veined or Pebbled and that of Talc carbonate is Soft. Properties of rock is another aspect for Charnockite vs Talc carbonate. The hardness of Charnockite is 6-7 and that of Talc carbonate is 1-2. The types of Charnockite are Enderbite whereas types of Talc carbonate are Not Available.
