Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

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.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Wehrlite vs Diabase 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 Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Diabase. Learn more about Wehrlite vs Diabase in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Wehrlite and Diabase, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Wehrlite and Diabase
Here you can know more about Wehrlite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Diabase consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Wehrlite is Rough and Banded and that of Diabase is Vesicular. Properties of rock is another aspect for Wehrlite vs Diabase. The hardness of Wehrlite is 5.5-6 and that of Diabase is 7. The types of Wehrlite are Ultramafic rock whereas types of Diabase are Dolerite. 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 Diabase is black. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Diabase is 0.84 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
