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.  
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Hornblendite vs Boninite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Hornblendite and Boninite Reserves. Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Hornblendite vs Boninite information and Hornblendite vs Boninite characteristics in the upcoming sections.

Hornblendite vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornblendite and Properties of Boninite. Learn more about Hornblendite vs Boninite 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 Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Hornblendite and Boninite, 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 Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Hornblendite and Boninite

Here you can know more about Hornblendite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Boninite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Boninite, 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, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Hornblendite is Foliated and that of Boninite is Dull and Soft. Properties of rock is another aspect for Hornblendite vs Boninite. The hardness of Hornblendite is 6-7 and that of Boninite is 7. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Boninite are Basalt. 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 Boninite is white. The specific heat capacity of Hornblendite is 0.84 kJ/Kg K and that of Boninite 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.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
