Formation

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 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 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 Latite and Tuff Reserves. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. 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 Latite vs Tuff information and Latite vs Tuff characteristics in the upcoming sections.

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

More about Latite and Tuff

Here you can know more about Latite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Tuff consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Latite is Rough and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Latite vs Tuff. The hardness of Latite is 5-5.5 and that of Tuff is 4-6. The types of Latite are Rhomb porphyries 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 Latite and Tuff is white. The specific heat capacity of Latite is 0.92 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.Latite is heat resistant, pressure resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
