5 Formation

5.1 Formation

Icelandite 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.

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Icelandite vs Tuff 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 Icelandite and Tuff Reserves. Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. 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 Icelandite vs Tuff information and Icelandite vs Tuff characteristics in the upcoming sections.
