Definition
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Novaculite and Marble
Here you can know more about Novaculite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Marble consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Novaculite is Glassy or Pearly and that of Marble is Veined and Shiny. Properties of rock is another aspect for Novaculite vs Marble. The hardness of Novaculite is 7 and that of Marble is 3-4. The types of Novaculite are Not Available whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. 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 Marble is white. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
