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.
Mangerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Novaculite and Mangerite
Here you can know more about Novaculite and Mangerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Mangerite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Mangerite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Mangerite, 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, Mangerite is available in black, brown, light to dark grey, white colors. Appearance of Novaculite is Glassy or Pearly and that of Mangerite is Shiny. Properties of rock is another aspect for Novaculite vs Mangerite. The hardness of Novaculite is 7 and that of Mangerite is 6-7. The types of Novaculite are Not Available whereas types of Mangerite 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 Mangerite is white. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Mangerite 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 Mangerite is heat resistant, impact resistant, pressure resistant.
