5.1 Formation

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

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

Quartzite vs Siltstone 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 Siltstone Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. 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 Siltstone information and Quartzite vs Siltstone characteristics in the upcoming sections.
