5.1 Formation

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.

Epidosite 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.

Siltstone vs Epidosite 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 Siltstone and Epidosite Reserves. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. 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 Siltstone vs Epidosite information and Siltstone vs Epidosite characteristics in the upcoming sections.
