Formation
Norite 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.

Norite 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. Norite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Norite and Properties of Travertine. Learn more about Norite vs Travertine in the next section. The interior uses of Norite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Norite and Travertine, they have various applications in construction industry. The uses of Norite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate 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 Norite and Travertine
Here you can know more about Norite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Travertine consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene 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 Norite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Norite is Veined and Shiny and that of Travertine is Fibrous. Properties of rock is another aspect for Norite vs Travertine. The hardness of Norite is 7 and that of Travertine is 3-4. The types of Norite 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 Norite is black while that of Travertine is white. The specific heat capacity of Norite 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.Norite is impact resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
