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.
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Jasperoid and Wehrlite
Here you can know more about Jasperoid and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Wehrlite consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Wehrlite, 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, Wehrlite is available in dark greenish - grey, green colors. Appearance of Jasperoid is Glassy or Pearly and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Jasperoid vs Wehrlite. The hardness of Jasperoid is 3.5-4 and that of Wehrlite is 5.5-6. The types of Jasperoid are Not Available whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jasperoid and Wehrlite is white. The specific heat capacity of Jasperoid is 0.92 kJ/Kg K and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
