Formation

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.   
Hornblendite 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 Hornblendite 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 Hornblendite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock. 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 Hornblendite information and Quartzite vs Hornblendite characteristics in the upcoming sections.
