5.1 Formation

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

Theralite 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.

Quartzite vs Theralite 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 Theralite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline. 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 Theralite information and Quartzite vs Theralite characteristics in the upcoming sections.

More about Quartzite and Theralite

Here you can know more about Quartzite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Theralite 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 Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Theralite, 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, Theralite is available in dark grey to black colors. Appearance of Quartzite is Lustrous and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Quartzite vs Theralite. The hardness of Quartzite is 6-7 and that of Theralite is 7. The types of Quartzite are Not Available whereas types of Theralite are Teschenite and Essexite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Theralite is white.
