Formation
Ijolite 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.

Ijolite 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. Ijolite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ijolite and Properties of Travertine. Learn more about Ijolite vs Travertine in the next section. The interior uses of Ijolite include Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Interior decoration and Kitchens whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Ijolite and Travertine, they have various applications in construction industry. The uses of Ijolite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories 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 Ijolite and Travertine
Here you can know more about Ijolite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Travertine consists of mineral content and compound content. The mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite 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 Ijolite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Ijolite is Banded and Foilated and that of Travertine is Fibrous. Properties of rock is another aspect for Ijolite vs Travertine. The hardness of Ijolite is 5.5-6 and that of Travertine is 3-4. The types of Ijolite 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 Ijolite and Travertine is white. The specific heat capacity of Ijolite is Not Available 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.Ijolite is heat resistant, impact resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
