5.1 Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

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.

Quartzite 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 Quartzite and Tuff Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite vs Tuff information and Quartzite vs Tuff characteristics in the upcoming sections.

Quartzite 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. Quartzite vs Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Tuff. Learn more about Quartzite vs Tuff in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Tuff, they have various applications in construction industry. The uses of Quartzite in construction industry include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone and that of Tuff include Building houses or walls, Construction aggregate.

More about Quartzite and Tuff

Here you can know more about Quartzite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Tuff consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Quartzite is Lustrous and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Quartzite vs Tuff. The hardness of Quartzite is 6-7 and that of Tuff is 4-6. The types of Quartzite are Not Available 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 Quartzite and Tuff is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Tuff is 0.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
