Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic 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.
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

More about Wehrlite and Minette
Here you can know more about Wehrlite and Minette. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Minette consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Minette, 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, Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Wehrlite is Rough and Banded and that of Minette is Dull, Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Minette. The hardness of Wehrlite is 5.5-6 and that of Minette is 5-6. The types of Wehrlite are Not Available whereas types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Minette is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Minette is Not Available. 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 Minette is heat resistant, impact resistant.
