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
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

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.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Mudstone vs Blueschist 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 Blueschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Blueschist. Learn more about Mudstone vs Blueschist in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Blueschist include Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Mudstone and Blueschist, 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 Blueschist include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Mudstone and Blueschist
Here you can know more about Mudstone and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Blueschist 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 Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Blueschist, 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, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Mudstone is Rough and Dull and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Mudstone vs Blueschist. The hardness of Mudstone is 2-3 and that of Blueschist is 3.5-4. The types of Mudstone are Marl, Shale and Argillite whereas types of Blueschist 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 Blueschist is white to grey. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Blueschist 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 Blueschist is impact resistant, pressure resistant.
