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.

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 Not Available 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 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.
