5 Formation

5.1 Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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.

Granulite 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 Granulite and Siltstone Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite vs Siltstone information and Granulite vs Siltstone characteristics in the upcoming sections.
