Archaeological Significance
Formation
Pantellerite 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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

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. Pantellerite vs Dunite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pantellerite and Properties of Dunite. Learn more about Pantellerite vs Dunite in the next section. The interior uses of Pantellerite include whereas the interior uses of Dunite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Pantellerite and Dunite, they have various applications in construction industry. The uses of Pantellerite in construction industry include and that of Dunite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Pantellerite and Dunite
Here you can know more about Pantellerite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Dunite consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Pantellerite is Layered and Foliated and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Pantellerite vs Dunite. The hardness of Pantellerite is 6-7 and that of Dunite is 3.5-4. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Dunite are Dunite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pantellerite is while that of Dunite is white. The specific heat capacity of Pantellerite is 0.84 kJ/Kg K and that of Dunite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pantellerite is heat resistant whereas Dunite is heat resistant, pressure resistant, wear resistant.
