Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
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
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
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.

Lamprophyre 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. Lamprophyre vs Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Wehrlite. Learn more about Lamprophyre vs Wehrlite in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lamprophyre and Wehrlite, they have various applications in construction industry. The uses of Lamprophyre in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Wehrlite include As dimension stone, Cobblestones.
More about Lamprophyre and Wehrlite
Here you can know more about Lamprophyre and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Wehrlite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Lamprophyre vs Wehrlite. The hardness of Lamprophyre is 5-6 and that of Wehrlite is 5.5-6. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite 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 Lamprophyre and Wehrlite is white. The specific heat capacity of Lamprophyre is 0.84 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.Lamprophyre is heat resistant, impact resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
