Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
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
Lherzolite 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.

Lherzolite 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. Lherzolite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lherzolite and Properties of Mudstone. Learn more about Lherzolite vs Mudstone in the next section. The interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Lherzolite and Mudstone, they have various applications in construction industry. The uses of Lherzolite in construction industry include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills. and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Lherzolite and Mudstone
Here you can know more about Lherzolite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Mudstone consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite 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 Lherzolite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Lherzolite vs Mudstone. The hardness of Lherzolite is 6.5 and that of Mudstone is 2-3. The types of Lherzolite are Garnet Lherzolite 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 Lherzolite and Mudstone is white. The specific heat capacity of Lherzolite is 0.95 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.Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
