Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

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.
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Wehrlite vs Argillite 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 Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Argillite. Learn more about Wehrlite vs Argillite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Wehrlite and Argillite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Argillite include Used for flooring, stair treads, borders and window sills..
More about Wehrlite and Argillite
Here you can know more about Wehrlite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Argillite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Argillite, 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, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Wehrlite is Rough and Banded and that of Argillite is Rough and Dull. Properties of rock is another aspect for Wehrlite vs Argillite. The hardness of Wehrlite is 5.5-6 and that of Argillite is 2-3. The types of Wehrlite are Not Available whereas types of Argillite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite is white while that of Argillite is white to grey. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Argillite is 0.87 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 Argillite is heat resistant, impact resistant.
