Formation
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.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Travertine vs Migmatite 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. Travertine vs Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Migmatite. Learn more about Travertine vs Migmatite in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Travertine and Migmatite, they have various applications in construction industry. The uses of Travertine in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar and that of Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Travertine and Migmatite
Here you can know more about Travertine and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Migmatite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Migmatite, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Travertine is Fibrous and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Travertine vs Migmatite. The hardness of Travertine is 3-4 and that of Migmatite is 5.5-6.5. The types of Travertine are Thermal Travertine and Tufa whereas types of Migmatite are Diatexites and Metatexites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine and Migmatite is white. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Migmatite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Travertine is impact resistant, pressure resistant, wear resistant whereas Migmatite is heat resistant, pressure resistant.
