5 Formation

5.1 Formation

Wehrlite 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.

Wehrlite 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 Wehrlite and Tuff Reserves. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. 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 Wehrlite vs Tuff information and Wehrlite vs Tuff characteristics in the upcoming sections.

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

More about Wehrlite and Tuff

Here you can know more about Wehrlite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Tuff consists of mineral content and compound content. The mineral content of Wehrlite includes 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 Wehrlite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Wehrlite vs Tuff. The hardness of Wehrlite is 5.5-6 and that of Tuff is 4-6. The types of Wehrlite 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 Wehrlite and Tuff is white. The specific heat capacity of Wehrlite is 0.63 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
