Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Tachylite 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 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.

Tachylite vs Travertine 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. Tachylite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tachylite and Properties of Travertine. Learn more about Tachylite vs Travertine in the next section. The interior uses of Tachylite include Decorative aggregates and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Tachylite and Travertine, they have various applications in construction industry. The uses of Tachylite in construction industry include Cutting tool, Knives, Landscaping, Scrapers and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.
More about Tachylite and Travertine
Here you can know more about Tachylite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Travertine consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Tachylite is Glassy and that of Travertine is Fibrous. Properties of rock is another aspect for Tachylite vs Travertine. The hardness of Tachylite is 5.5 and that of Travertine is 3-4. The types of Tachylite are Not Available whereas types of Travertine are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion while that of Travertine is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tachylite is heat resistant, impact resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
