5.1 Formation

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.

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

Tuff vs Trachyte 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 Tuff and Trachyte Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar. 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 Tuff vs Trachyte information and Tuff vs Trachyte characteristics in the upcoming sections.
