Formation
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
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.

Shonkinite 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. Shonkinite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shonkinite and Properties of Travertine. Learn more about Shonkinite vs Travertine in the next section. The interior uses of Shonkinite include Decorative aggregates, Flooring, 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 Shonkinite and Travertine, they have various applications in construction industry. The uses of Shonkinite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories 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 Shonkinite and Travertine
Here you can know more about Shonkinite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shonkinite and Travertine consists of mineral content and compound content. The mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Shonkinite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Shonkinite is available in brown, buff, cream, green, grey, pink, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Shonkinite is Banded and Foilated and that of Travertine is Fibrous. Properties of rock is another aspect for Shonkinite vs Travertine. The hardness of Shonkinite is 5.5-6 and that of Travertine is 3-4. The types of Shonkinite 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 Shonkinite and Travertine is white. The specific heat capacity of Shonkinite is 0.92 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.Shonkinite is heat resistant, impact resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
