5 Formation
5.1 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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

Tuff vs Soapstone 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 Soapstone Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. 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 Soapstone information and Tuff vs Soapstone characteristics in the upcoming sections.

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

More about Tuff and Soapstone

Here you can know more about Tuff and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Soapstone consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Tuff vs Soapstone. The hardness of Tuff is 4-6 and that of Soapstone is 1. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Soapstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tuff is white while that of Soapstone is black. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Soapstone is 0.88 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 Soapstone is heat resistant, pressure resistant.
