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
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

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.
Foidolites 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 Foidolite 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 Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Foidolite. Learn more about Mudstone vs Foidolite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mudstone and Foidolite, 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 Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Mudstone and Foidolite
Here you can know more about Mudstone and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Foidolite 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 Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Foidolite, 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, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Mudstone is Rough and Dull and that of Foidolite is Dull. Properties of rock is another aspect for Mudstone vs Foidolite. The hardness of Mudstone is 2-3 and that of Foidolite is 1.5. The types of Mudstone are Marl, Shale and Argillite whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Foidolite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Foidolite is 0.79 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 Foidolite is heat resistant, wear resistant.
