Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Constitutes upper part of the Earth's mantle, Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of 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.

Claystone 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. Claystone vs Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Wehrlite. Learn more about Claystone vs Wehrlite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Claystone and Wehrlite, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, 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 Claystone and Wehrlite
Here you can know more about Claystone and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Wehrlite consists of mineral content and compound content. The mineral content of Claystone 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 Claystone vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Claystone 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 Claystone is Rough and Dull and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Claystone vs Wehrlite. The hardness of Claystone is 3.5-4 and that of Wehrlite is 5.5-6. The types of Claystone are Claystone whereas types of Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Wehrlite is white. The specific heat capacity of Claystone is 0.92 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.Claystone is heat resistant, impact resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
