Archaeological Significance
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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

Wehrlite vs Jaspillite 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 Jaspillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Jaspillite. Learn more about Wehrlite vs Jaspillite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Jaspillite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Wehrlite and Jaspillite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Jaspillite 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.
More about Wehrlite and Jaspillite
Here you can know more about Wehrlite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Jaspillite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Jaspillite, 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, Jaspillite is available in red, reddish brown colors. Appearance of Wehrlite is Rough and Banded and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Wehrlite vs Jaspillite. The hardness of Wehrlite is 5.5-6 and that of Jaspillite is 3. The types of Wehrlite are Ultramafic rock whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Jaspillite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Jaspillite is 3.20 kJ/Kg K.
