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.
Nephelinite 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 Nephelinite 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 Nephelinite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).. 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 Nephelinite information and Travertine vs Nephelinite characteristics in the upcoming sections.

Travertine vs Nephelinite 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 Nephelinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Nephelinite. Learn more about Travertine vs Nephelinite in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Nephelinite include Decorative aggregates, Homes and Interior decoration.

More about Travertine and Nephelinite

Here you can know more about Travertine and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Nephelinite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Nephelinite, 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, Nephelinite is available in black, brown, colourless, green, grey, white colors. Appearance of Travertine is Fibrous and that of Nephelinite is Skeletal. Properties of rock is another aspect for Travertine vs Nephelinite. The hardness of Travertine is 3-4 and that of Nephelinite is 6.5. The types of Travertine are Not Available whereas types of Nephelinite are Peralkaline Nephelinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine and Nephelinite is white. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Nephelinite is 0.88 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 Nephelinite is heat resistant.
