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

More about Novaculite and Jadeitite
Here you can know more about Novaculite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Jadeitite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Jadeitite, 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, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Novaculite is Glassy or Pearly and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Novaculite vs Jadeitite. The hardness of Novaculite is 7 and that of Jadeitite is 3-5. The types of Novaculite are Not Available whereas types of Jadeitite 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 Jadeitite is white, greenish white or grey. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Jadeitite 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 Jadeitite is heat resistant, water resistant.
