Formation
Foidolites 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.
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.

Foidolite vs Jadeitite 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. Foidolite vs Jadeitite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Jadeitite. Learn more about Foidolite vs Jadeitite in the next section. The interior uses of Foidolite include Decorative aggregates and Interior decoration whereas the interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Foidolite and Jadeitite, they have various applications in construction industry. The uses of Foidolite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Jadeitite include As dimension stone, Cutting tool, Knives.
More about Foidolite and Jadeitite
Here you can know more about Foidolite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Jadeitite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Foidolite is Dull and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Foidolite vs Jadeitite. The hardness of Foidolite is 1.5 and that of Jadeitite is 3-5. The types of Foidolite are Igneous rock whereas types of Jadeitite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Foidolite is 0.79 kJ/Kg K and that of Jadeitite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Foidolite is heat resistant, wear resistant whereas Jadeitite is heat resistant, water resistant.
