Archaeological Significance
Formation
Pyrolite 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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Pyrolite vs Turbidite 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. Pyrolite vs Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Turbidite. Learn more about Pyrolite vs Turbidite in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Pyrolite and Turbidite, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Pyrolite and Turbidite
Here you can know more about Pyrolite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Turbidite consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Pyrolite is Rough and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Pyrolite vs Turbidite. The hardness of Pyrolite is 5.5-6 and that of Turbidite is 3. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyrolite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Pyrolite is 1.25 kJ/Kg K and that of Turbidite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
