Definition
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro
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
Troctolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive 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.

Troctolite 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. Troctolite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Troctolite and Properties of Mudstone. Learn more about Troctolite vs Mudstone in the next section. The interior uses of Troctolite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Interior decoration and Kitchens whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Troctolite and Mudstone, they have various applications in construction industry.

More about Troctolite and Mudstone
Here you can know more about Troctolite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Mudstone consists of mineral content and compound content. The mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene 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 Troctolite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Troctolite is available in dark grey to black colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Troctolite is Veined and Shiny and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Troctolite vs Mudstone. The hardness of Troctolite is 7 and that of Mudstone is 2-3. The types of Troctolite are Ultramafic rock 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 Troctolite is black while that of Mudstone is white. The specific heat capacity of Troctolite 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.Troctolite is impact resistant, pressure resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
