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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

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