5.1 Formation
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.
When the lava is released from volcano, it undergoes a very rapid cooling which freezes the mechanisms of crystallization. The result is a volcanic glass with a uniform smooth texture.

Travertine vs Obsidian 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 Travertine and Obsidian Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. 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 Travertine vs Obsidian information and Travertine vs Obsidian characteristics in the upcoming sections.

Travertine vs Obsidian Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Travertine vs Obsidian characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Obsidian. Learn more about Travertine vs Obsidian in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Obsidian include Decorative aggregates and Interior decoration.
