Definition
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass
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

Formation
Shoshonite 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 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.

Shoshonite vs Mudstone 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. Shoshonite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shoshonite and Properties of Mudstone. Learn more about Shoshonite vs Mudstone in the next section. The interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Shoshonite and Mudstone, they have various applications in construction industry. The uses of Shoshonite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Shoshonite and Mudstone
Here you can know more about Shoshonite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Mudstone consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Shoshonite is Dull and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Shoshonite vs Mudstone. The hardness of Shoshonite is 6 and that of Mudstone is 2-3. The types of Shoshonite are Not Available whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite is white to grey while that of Mudstone is white. The specific heat capacity of Shoshonite is Not Available and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shoshonite is heat resistant, pressure resistant whereas Mudstone is heat resistant, impact resistant.
