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
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

From the English mud and stone, from low German mudde and stainaz
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Archaeological Significance
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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Mudstone vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Turbidite. Learn more about Mudstone vs Turbidite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Mudstone and Turbidite, 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 Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Mudstone and Turbidite
Here you can know more about Mudstone and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Turbidite 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 Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Turbidite, 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, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Mudstone is Rough and Dull and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Mudstone vs Turbidite. The hardness of Mudstone is 2-3 and that of Turbidite is 3. The types of Mudstone are Marl, Shale and Argillite whereas types of Turbidite are Sedimentary rock. 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 Turbidite is white, greenish white or grey. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Turbidite 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 Turbidite is heat resistant.
