5 Formation

5.1 Formation

Foidolites 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 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.

Foidolite 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 Foidolite and Siltstone Reserves. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. 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.
