Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Jadeitite vs Pyrolite 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. Jadeitite vs Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jadeitite and Properties of Pyrolite. Learn more about Jadeitite vs Pyrolite in the next section. The interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Jadeitite and Pyrolite, they have various applications in construction industry. The uses of Jadeitite in construction industry include As dimension stone, Cutting tool, Knives and that of Pyrolite include As dimension stone, Cobblestones.
More about Jadeitite and Pyrolite
Here you can know more about Jadeitite and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Pyrolite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Pyrolite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, green, grey, white colors whereas, Pyrolite is available in dark greenish - grey colors. Appearance of Jadeitite is Rough and Dull and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Jadeitite vs Pyrolite. The hardness of Jadeitite is 3-5 and that of Pyrolite is 5.5-6. The types of Jadeitite are Metamorphic rock whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Pyrolite is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Pyrolite 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.Jadeitite is heat resistant, water resistant whereas Pyrolite is heat resistant, pressure resistant, wear resistant.
