Formation
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.
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.

Novaculite 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. Novaculite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Novaculite and Properties of Travertine. Learn more about Novaculite vs Travertine in the next section. The interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Novaculite and Travertine, they have various applications in construction industry. The uses of Novaculite in construction industry include Arrowheads, Building houses or walls, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Knives, Landscaping, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone, Spear points, Used to sharpen metal tools and weapons 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 Novaculite and Travertine
Here you can know more about Novaculite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Travertine consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Novaculite is available in black, brown, green, grey, red, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Novaculite is Glassy or Pearly and that of Travertine is Fibrous. Properties of rock is another aspect for Novaculite vs Travertine. The hardness of Novaculite is 7 and that of Travertine is 3-4. The types of Novaculite are Sedimentary 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 Novaculite is while that of Travertine is white. The specific heat capacity of Novaculite is 0.74 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.Novaculite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
