Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Archaeological Significance
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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Wehrlite vs Oolite 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 Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Oolite. Learn more about Wehrlite vs Oolite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Wehrlite and Oolite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Wehrlite and Oolite
Here you can know more about Wehrlite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Oolite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Oolite, 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, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Wehrlite vs Oolite. The hardness of Wehrlite is 5.5-6 and that of Oolite is 3-4. The types of Wehrlite are Ultramafic rock whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Oolite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Oolite is 0.65 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 Oolite is heat resistant, wear resistant.
