5 Formation
5.1 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.
Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Hornblendite vs Tuff 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 Tuff Reserves. Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. 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 Tuff information and Hornblendite vs Tuff characteristics in the upcoming sections.

Hornblendite vs Tuff 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 Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornblendite and Properties of Tuff. Learn more about Hornblendite vs Tuff 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 Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration.

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 Tuff include Building houses or walls, Construction aggregate.

More about Hornblendite and Tuff

Here you can know more about Hornblendite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Tuff consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Tuff, 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, Tuff is available in brown, grey, yellow colors. Appearance of Hornblendite is Foliated and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Hornblendite vs Tuff. The hardness of Hornblendite is 6-7 and that of Tuff is 4-6. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. 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 Tuff is white.
