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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Wehrlite vs Dacite 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 Dacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Dacite. Learn more about Wehrlite vs Dacite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Wehrlite and Dacite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Dacite include As dimension stone, Construction aggregate, For road aggregate, Landscaping.
More about Wehrlite and Dacite
Here you can know more about Wehrlite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Dacite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Dacite, 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, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Wehrlite is Rough and Banded and that of Dacite is Vesicular. Properties of rock is another aspect for Wehrlite vs Dacite. The hardness of Wehrlite is 5.5-6 and that of Dacite is 2-2.25. The types of Wehrlite are Not Available whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Dacite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Dacite 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 Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
