Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Metapelite and Charnockite

Here you can know more about Metapelite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Charnockite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Metapelite is Banded and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Metapelite vs Charnockite. The hardness of Metapelite is 5-6 and that of Charnockite is 6-7. The types of Metapelite are Metamorphic rock whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is while that of Charnockite is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K.
