Definition
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Novaculite vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Novaculite and Properties of Talc carbonate. Learn more about Novaculite vs Talc carbonate in the next section. The interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Novaculite and Talc carbonate, 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 Talc carbonate include Source of calcium.
More about Novaculite and Talc carbonate
Here you can know more about Novaculite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Talc carbonate consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Talc carbonate, 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, Talc carbonate is available in colourless, grey, white colors. Appearance of Novaculite is Glassy or Pearly and that of Talc carbonate is Soft. Properties of rock is another aspect for Novaculite vs Talc carbonate. The hardness of Novaculite is 7 and that of Talc carbonate is 1-2. The types of Novaculite are Not Available whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Novaculite is colorless while that of Talc carbonate is white. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
