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
Aplite is a fine-grained granite composed mainly of feldspar and quartz

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.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Mudstone vs Aplite 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 Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Aplite. Learn more about Mudstone vs Aplite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Mudstone and Aplite, 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 Aplite include As dimension stone.
More about Mudstone and Aplite
Here you can know more about Mudstone and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Aplite 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 Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Aplite, 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, Aplite is available in black, grey, orange, pink, white colors. Appearance of Mudstone is Rough and Dull and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Mudstone vs Aplite. The hardness of Mudstone is 2-3 and that of Aplite is 6.5. The types of Mudstone are Marl, Shale and Argillite whereas types of Aplite 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 Aplite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Aplite 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 Aplite is heat resistant, wear resistant.
