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.
Trachyandesite 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 some exceptional properties of Jadeitite and Trachyandesite, they have various applications in construction industry. The uses of Jadeitite in construction industry include As dimension stone, Cutting tool, Knives and that of Trachyandesite include Building houses or walls, Cobblestones, For road aggregate, Rail track ballast, Roadstone.
More about Jadeitite and Trachyandesite
Here you can know more about Jadeitite and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Trachyandesite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Trachyandesite, 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, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Jadeitite is Rough and Dull and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Jadeitite vs Trachyandesite. The hardness of Jadeitite is 3-5 and that of Trachyandesite is 4-5. The types of Jadeitite are Metamorphic rock whereas types of Trachyandesite are Basaltic Trachyandesite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite is white, greenish white or grey while that of Trachyandesite is light to dark brown. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Trachyandesite is 0.84 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 Trachyandesite is heat resistant, pressure resistant, wear resistant.
