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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

More about Metapelite and Jasperoid
Here you can know more about Metapelite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Jasperoid consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Jasperoid, 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, Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Metapelite is Banded and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Metapelite vs Jasperoid. The hardness of Metapelite is 5-6 and that of Jasperoid is 3.5-4. The types of Metapelite are Not Available whereas types of Jasperoid are Not Available. 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 Jasperoid is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Jasperoid 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Jasperoid is heat resistant, pressure resistant, wear resistant.
