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
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Mudstone vs Conglomerate 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 Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Conglomerate. Learn more about Mudstone vs Conglomerate in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Mudstone and Conglomerate, 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 Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Mudstone and Conglomerate
Here you can know more about Mudstone and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Conglomerate 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 Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all . When we have to compare Mudstone vs Conglomerate, 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, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Mudstone is Rough and Dull and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Mudstone vs Conglomerate. Hardness of Mudstone and Conglomerate is 2-3. The types of Mudstone are Marl, Shale and Argillite whereas types of Conglomerate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Conglomerate is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Conglomerate 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 Conglomerate is heat resistant.
