Formation
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.

Hornblendite vs Foidolite 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. Hornblendite vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornblendite and Properties of Foidolite. Learn more about Hornblendite vs Foidolite in the next section. The interior uses of Hornblendite include Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Hornblendite and Foidolite, they have various applications in construction industry. The uses of Hornblendite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Hornblendite and Foidolite
Here you can know more about Hornblendite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Foidolite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Hornblendite is Foliated and that of Foidolite is Dull. Properties of rock is another aspect for Hornblendite vs Foidolite. The hardness of Hornblendite is 6-7 and that of Foidolite is 1.5. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Foidolite is white. The specific heat capacity of Hornblendite is 0.84 kJ/Kg K and that of Foidolite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Foidolite is heat resistant, wear resistant.
