Formation
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.
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 vs Jasperoid Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Wehrlite vs Jasperoid characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Jasperoid. Learn more about Wehrlite vs Jasperoid in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Jasperoid include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Wehrlite and Jasperoid, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Jasperoid include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Wehrlite and Jasperoid
Here you can know more about Wehrlite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Jasperoid consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Jasperoid, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Wehrlite vs Jasperoid. The hardness of Wehrlite is 5.5-6 and that of Jasperoid is 3.5-4. The types of Wehrlite 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 Wehrlite and Jasperoid is white. The specific heat capacity of Wehrlite is 0.63 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Jasperoid is heat resistant, pressure resistant, wear resistant.
