Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock

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.
Hornblendite 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.

More about Wehrlite and Hornblendite
Here you can know more about Wehrlite and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Hornblendite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Hornblendite, 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, Hornblendite is available in black, brown, green, grey colors. Appearance of Wehrlite is Rough and Banded and that of Hornblendite is Foliated. Properties of rock is another aspect for Wehrlite vs Hornblendite. The hardness of Wehrlite is 5.5-6 and that of Hornblendite is 6-7. The types of Wehrlite are Not Available whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. 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 Hornblendite is white to grey. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Hornblendite 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 Hornblendite is heat resistant, pressure resistant, wear resistant.
