Formation
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.
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.

More about Jasperoid and Metapelite
Here you can know more about Jasperoid and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Metapelite consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Jasperoid is Glassy or Pearly and that of Metapelite is Banded. Properties of rock is another aspect for Jasperoid vs Metapelite. The hardness of Jasperoid is 3.5-4 and that of Metapelite is 5-6. The types of Jasperoid are Not Available whereas types of Metapelite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jasperoid is white while that of Metapelite is unknown. The specific heat capacity of Jasperoid is 0.92 kJ/Kg K and that of Metapelite is 0.72 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Jasperoid is heat resistant, pressure resistant, wear resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
