Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
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.

Andesite 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. Andesite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Andesite and Properties of Travertine. Learn more about Andesite vs Travertine in the next section. The interior uses of Andesite include Decorative aggregates, Floor tiles, 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 Andesite and Travertine, they have various applications in construction industry. The uses of Andesite in construction industry include Cobblestones, 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 Andesite and Travertine
Here you can know more about Andesite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Travertine consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon 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 Andesite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Andesite is Dull and Soft and that of Travertine is Fibrous. Properties of rock is another aspect for Andesite vs Travertine. The hardness of Andesite is 7 and that of Travertine is 3-4. The types of Andesite are Icelandite 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 Andesite and Travertine is white. The specific heat capacity of Andesite is 2.39 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.Andesite is heat resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
