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
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

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.
Teschenite 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 Teschenite 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 Teschenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Teschenite. Learn more about Mudstone vs Teschenite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Mudstone and Teschenite, 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 Teschenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Mudstone and Teschenite
Here you can know more about Mudstone and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Teschenite 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 Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Mudstone is Rough and Dull and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Mudstone vs Teschenite. The hardness of Mudstone is 2-3 and that of Teschenite is 7. The types of Mudstone are Marl, Shale and Argillite whereas types of Teschenite are Not Available. 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 Teschenite is black. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Teschenite is Not Available. 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 Teschenite is impact resistant, pressure resistant, wear resistant.
