Definition
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar
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

Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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.

Charnockite vs Mudstone 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. Charnockite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Mudstone. Learn more about Charnockite vs Mudstone in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Charnockite and Mudstone, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Charnockite and Mudstone
Here you can know more about Charnockite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Mudstone consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Charnockite is Veined or Pebbled and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Charnockite vs Mudstone. The hardness of Charnockite is 6-7 and that of Mudstone is 2-3. The types of Charnockite are Enderbite whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Mudstone is white. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Charnockite is heat resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
