Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
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.

Mudstone vs Wehrlite 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. Mudstone vs Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Wehrlite. Learn more about Mudstone vs Wehrlite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mudstone and Wehrlite, they have various applications in construction industry. The uses of Mudstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Wehrlite include As dimension stone, Cobblestones.
More about Mudstone and Wehrlite
Here you can know more about Mudstone and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Wehrlite consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Mudstone is Rough and Dull and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Mudstone vs Wehrlite. The hardness of Mudstone is 2-3 and that of Wehrlite is 5.5-6. The types of Mudstone are Marl, Shale and Argillite whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Wehrlite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Wehrlite is 0.63 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mudstone is heat resistant, impact resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
