1.1 Definition

Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

5 Formation

5.1 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.

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Wehrlite vs Shale Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Wehrlite and Shale Reserves. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Wehrlite vs Shale information and Wehrlite vs Shale characteristics in the upcoming sections.

Wehrlite vs Shale 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 Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Shale. Learn more about Wehrlite vs Shale in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Wehrlite and Shale, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Wehrlite and Shale

Here you can know more about Wehrlite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Shale consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Shale, 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, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Shale is Muddy. Properties of rock is another aspect for Wehrlite vs Shale. The hardness of Wehrlite is 5.5-6 and that of Shale is 3. The types of Wehrlite are Not Available whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Shale is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Shale is 0.39 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 Shale is heat resistant, impact resistant.
