Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

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.
Troctolite 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 Troctolite 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 Troctolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Troctolite. Learn more about Travertine vs Troctolite in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Troctolite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Travertine and Troctolite, they have various applications in construction industry.

More about Travertine and Troctolite
Here you can know more about Travertine and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Troctolite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Troctolite, 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, Troctolite is available in dark grey to black colors. Appearance of Travertine is Fibrous and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Travertine vs Troctolite. The hardness of Travertine is 3-4 and that of Troctolite is 7. The types of Travertine are Thermal Travertine and Tufa whereas types of Troctolite are Ultramafic rock. 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 Troctolite is black. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Troctolite is 0.84 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 Troctolite is impact resistant, pressure resistant, wear resistant.
