Formation

Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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.

Quartzite vs Trachyte Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Quartzite and Trachyte Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Quartzite vs Trachyte information and Quartzite vs Trachyte characteristics in the upcoming sections.

Quartzite vs Trachyte 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. Quartzite vs Trachyte characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Trachyte. Learn more about Quartzite vs Trachyte in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Trachyte include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Trachyte, they have various applications in construction industry. The uses of Quartzite in construction industry include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone and that of Trachyte 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.

More about Quartzite and Trachyte

Here you can know more about Quartzite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Trachyte consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Trachyte, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Quartzite is Lustrous and that of Trachyte is Banded. Properties of rock is another aspect for Quartzite vs Trachyte. The hardness of Quartzite is 6-7 and that of Trachyte is 6. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Trachyte are Felsic volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Trachyte is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Trachyte 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.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Trachyte is heat resistant, impact resistant, wear resistant.
