Formation

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.

Latite 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 vs Latite 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 Tuff and Latite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. 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 Tuff vs Latite information and Tuff vs Latite characteristics in the upcoming sections.

Tuff vs Latite 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. Tuff vs Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tuff and Properties of Latite. Learn more about Tuff vs Latite in the next section. The interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Tuff and Latite, they have various applications in construction industry. The uses of Tuff in construction industry include Building houses or walls, Construction aggregate and that of Latite 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 Tuff and Latite

Here you can know more about Tuff and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Latite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Latite is Rough. Properties of rock is another aspect for Tuff vs Latite. The hardness of Tuff is 4-6 and that of Latite is 5-5.5. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tuff and Latite is white. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Latite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tuff is heat resistant, impact resistant, pressure resistant, wear resistant whereas Latite is heat resistant, pressure resistant.
