Definition
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Due to some exceptional properties of Basaltic Trachyandesite and Serpentinite, they have various applications in construction industry. The uses of Basaltic Trachyandesite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Basaltic Trachyandesite and Serpentinite
Here you can know more about Basaltic Trachyandesite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Serpentinite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Basaltic Trachyandesite vs Serpentinite. The hardness of Basaltic Trachyandesite is 6 and that of Serpentinite is 3-5. The types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basaltic Trachyandesite is white to grey while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Basaltic Trachyandesite is 0.84 kJ/Kg K and that of Serpentinite 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.Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Serpentinite is heat resistant.
