Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

More about Travertine and Adakite
Here you can know more about Travertine and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Adakite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Travertine is Fibrous and that of Adakite is Dull and Soft. Properties of rock is another aspect for Travertine vs Adakite. Hardness of Travertine and Adakite is 3-4. The types of Travertine are Thermal Travertine and Tufa whereas types of Adakite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Adakite is bluish black. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Adakite is 0.84 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 Adakite is heat resistant, pressure resistant, wear resistant.
