More about Novaculite and Evaporite

Here you can know more about Novaculite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Evaporite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Evaporite, 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, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Novaculite is Glassy or Pearly and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Novaculite vs Evaporite. The hardness of Novaculite is 7 and that of Evaporite is 2-3. The types of Novaculite are Not Available whereas types of Evaporite 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 Evaporite is white. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Evaporite 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 Evaporite is heat resistant, pressure resistant.
