Definition
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar
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
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
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.

Trachyte vs Serpentinite 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. Trachyte vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Trachyte and Properties of Serpentinite. Learn more about Trachyte vs Serpentinite in the next section. The interior uses of Trachyte include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Trachyte and Serpentinite, they have various applications in construction industry. The uses of Trachyte in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Trachyte and Serpentinite
Here you can know more about Trachyte and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyte and Serpentinite consists of mineral content and compound content. The mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz 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 Trachyte vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Trachyte is Banded and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Trachyte vs Serpentinite. The hardness of Trachyte is 6 and that of Serpentinite is 3-5. The types of Trachyte are Not Available 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 Trachyte is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Trachyte is Not Available 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.Trachyte is heat resistant, impact resistant, wear resistant whereas Serpentinite is heat resistant.
