Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
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.

Anorthosite 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. Anorthosite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Travertine. Learn more about Anorthosite vs Travertine in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Anorthosite and Travertine, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, 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 Anorthosite and Travertine
Here you can know more about Anorthosite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Travertine consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene 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 Anorthosite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Travertine is Fibrous. Properties of rock is another aspect for Anorthosite vs Travertine. The hardness of Anorthosite is 5-6 and that of Travertine is 3-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite 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 Anorthosite and Travertine is white. The specific heat capacity of Anorthosite is 0.84 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
