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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

Novaculite vs Diorite 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 Diorite Reserves. Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene. 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 Diorite information and Novaculite vs Diorite characteristics in the upcoming sections.

Novaculite vs Diorite 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 Diorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Novaculite and Properties of Diorite. Learn more about Novaculite vs Diorite in the next section. The interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Diorite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Novaculite and Diorite, they have various applications in construction industry.

More about Novaculite and Diorite

Here you can know more about Novaculite and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Diorite consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Diorite 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 Diorite, 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, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Novaculite is Glassy or Pearly and that of Diorite is Shiny. Properties of rock is another aspect for Novaculite vs Diorite. The hardness of Novaculite is 7 and that of Diorite is 6-7. The types of Novaculite are Sedimentary rock whereas types of Diorite are Plagioclase Diorite and Quartz Diorite. 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 Diorite is bluish black. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Diorite is 0.84 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 Diorite is heat resistant, pressure resistant, wear resistant.
