1 Definition
1.1 Definition
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
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

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.
Felsite 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.

Mudstone vs Felsite 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 Felsite 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. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. 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 Felsite information and Mudstone vs Felsite characteristics in the upcoming sections.

Mudstone vs Felsite 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 Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Felsite. Learn more about Mudstone vs Felsite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Mudstone and Felsite, 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 Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.

More about Mudstone and Felsite

Here you can know more about Mudstone and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Felsite 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 Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Felsite, 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, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Mudstone is Rough and Dull and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mudstone vs Felsite. The hardness of Mudstone is 2-3 and that of Felsite is 5-5.5. The types of Mudstone are Marl, Shale and Argillite whereas types of Felsite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Felsite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Felsite 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.Mudstone is heat resistant, impact resistant whereas Felsite is heat resistant, impact resistant.
