Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

More about Appinite and Travertine
Here you can know more about Appinite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Travertine consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, 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 Appinite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Appinite is Dull, Banded and Foilated and that of Travertine is Fibrous. Properties of rock is another aspect for Appinite vs Travertine. The hardness of Appinite is 5-6 and that of Travertine is 3-4. The types of Appinite are Igneous rock whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Appinite and Travertine is white. The specific heat capacity of Appinite 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.Appinite is heat resistant, impact resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
