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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Mudstone vs Pumice 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 Pumice 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. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Pumice information and Mudstone vs Pumice characteristics in the upcoming sections.

Mudstone vs Pumice 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 Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Pumice. Learn more about Mudstone vs Pumice in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Mudstone and Pumice, 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 Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.

More about Mudstone and Pumice

Here you can know more about Mudstone and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Pumice 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 Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Pumice, 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, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Mudstone is Rough and Dull and that of Pumice is Vesicular. Properties of rock is another aspect for Mudstone vs Pumice. The hardness of Mudstone is 2-3 and that of Pumice is 6. The types of Mudstone are Marl, Shale and Argillite whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone is white while that of Pumice is white, greenish white or grey. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
