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.

Tephrite 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.

Travertine vs Tephrite 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 Tephrite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Tephrite is an aphanitic to porphyritic textured, volcanic igneous rock. 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 Tephrite information and Travertine vs Tephrite characteristics in the upcoming sections.

More about Travertine and Tephrite

Here you can know more about Travertine and Tephrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Tephrite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Tephrite includes Alkali feldspar, Nepheline, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Tephrite, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Tephrite is available in black, brown, colourless, green, grey, white colors. Appearance of Travertine is Fibrous and that of Tephrite is Vesicular. Properties of rock is another aspect for Travertine vs Tephrite. The hardness of Travertine is 3-4 and that of Tephrite is 6.5. The types of Travertine are Not Available whereas types of Tephrite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Tephrite is bluish black. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Tephrite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Travertine is impact resistant, pressure resistant, wear resistant whereas Tephrite is heat resistant, impact resistant.
