Formation

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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Novaculite vs Granulite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Novaculite and Granulite Reserves. Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Novaculite vs Granulite information and Novaculite vs Granulite characteristics in the upcoming sections.

Novaculite vs Granulite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Novaculite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Novaculite and Properties of Granulite. Learn more about Novaculite vs Granulite in the next section.

More about Novaculite and Granulite

Here you can know more about Novaculite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Granulite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Novaculite is Glassy or Pearly and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Novaculite vs Granulite. The hardness of Novaculite is 7 and that of Granulite is 6-7. The types of Novaculite are Sedimentary rock whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Novaculite is while that of Granulite is white. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
