Formation
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 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 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. Trachyandesite vs Jadeitite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Trachyandesite and Properties of Jadeitite. Learn more about Trachyandesite vs Jadeitite in the next section. The interior uses of Trachyandesite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Trachyandesite and Jadeitite, they have various applications in construction industry. The uses of Trachyandesite in construction industry include Building houses or walls, Cobblestones, For road aggregate, Rail track ballast, Roadstone and that of Jadeitite include As dimension stone, Cutting tool, Knives.
More about Trachyandesite and Jadeitite
Here you can know more about Trachyandesite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyandesite and Jadeitite consists of mineral content and compound content. The mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase 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 Trachyandesite vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Trachyandesite is available in black, brown, light to dark grey colors whereas, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Trachyandesite is Dull and Soft and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Trachyandesite vs Jadeitite. The hardness of Trachyandesite is 4-5 and that of Jadeitite is 3-5. The types of Trachyandesite are Basaltic Trachyandesite whereas types of Jadeitite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trachyandesite is light to dark brown while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Trachyandesite is 0.84 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.Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Jadeitite is heat resistant, water resistant.
