5 Formation
5.1 Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
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.

Mudstone 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 Mudstone and Tuff Reserves. Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations. 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 Mudstone vs Tuff information and Mudstone vs Tuff characteristics in the upcoming sections.

Mudstone 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. Mudstone vs Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Tuff. Learn more about Mudstone vs Tuff in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Mudstone and Tuff, they have various applications in construction industry. The uses of Mudstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Tuff include Building houses or walls, Construction aggregate.

More about Mudstone and Tuff

Here you can know more about Mudstone and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Tuff consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Mudstone is Rough and Dull and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Mudstone vs Tuff. The hardness of Mudstone is 2-3 and that of Tuff is 4-6. The types of Mudstone are Marl, Shale and Argillite 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 Mudstone and Tuff is white. The specific heat capacity of Mudstone is 0.39 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.Mudstone is heat resistant, impact resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
