Formation

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.   
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Quartzite vs Migmatite 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 Migmatite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. 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 Migmatite information and Quartzite vs Migmatite characteristics in the upcoming sections.

Quartzite vs Migmatite 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 Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Migmatite. Learn more about Quartzite vs Migmatite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Quartzite and Migmatite, 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 Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Quartzite and Migmatite

Here you can know more about Quartzite and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Migmatite 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 Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Migmatite, 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, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Quartzite is Lustrous and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Quartzite vs Migmatite. The hardness of Quartzite is 6-7 and that of Migmatite is 5.5-6.5. The types of Quartzite are Not Available whereas types of Migmatite are Diatexites and Metatexites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Migmatite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Migmatite is Not Available. 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 Migmatite is heat resistant, pressure resistant.
