Definition
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Archaeological Significance
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Novaculite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Novaculite and Properties of Serpentinite. Learn more about Novaculite vs Serpentinite in the next section. The interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Novaculite and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Novaculite and Serpentinite
Here you can know more about Novaculite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Serpentinite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Serpentinite, 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, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Novaculite is Glassy or Pearly and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Novaculite vs Serpentinite. The hardness of Novaculite is 7 and that of Serpentinite is 3-5. The types of Novaculite are Sedimentary rock whereas types of Serpentinite are Jadeitite. 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 Serpentinite is white, greenish white or grey. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
