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.

Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Tuff vs Suevite 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 Suevite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.. 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 Suevite information and Tuff vs Suevite characteristics in the upcoming sections.

More about Tuff and Suevite

Here you can know more about Tuff and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Suevite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all . When we have to compare Tuff vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Suevite is Banded. Properties of rock is another aspect for Tuff vs Suevite. The hardness of Tuff is 4-6 and that of Suevite is 5.5. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Suevite 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 Suevite is heat resistant.
