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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Metapelite and Andesite
Here you can know more about Metapelite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Andesite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Metapelite is Banded and that of Andesite is Dull and Soft. Properties of rock is another aspect for Metapelite vs Andesite. The hardness of Metapelite is 5-6 and that of Andesite is 7. The types of Metapelite are Not Available whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is unknown while that of Andesite is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Metapelite is heat resistant, impact resistant, pressure resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
