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.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Novaculite vs Diabase 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 Diabase Reserves. Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. 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 Diabase information and Novaculite vs Diabase characteristics in the upcoming sections.

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

More about Novaculite and Diabase

Here you can know more about Novaculite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Novaculite and Diabase consists of mineral content and compound content. The mineral content of Novaculite includes Quartz, Silicon and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Sedimentary Rocks. When we have to compare Novaculite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Novaculite is Glassy or Pearly and that of Diabase is Vesicular. Properties of rock is another aspect for Novaculite vs Diabase. Hardness of Novaculite and Diabase is 7. The types of Novaculite are Sedimentary rock whereas types of Diabase are Dolerite. 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 Diabase is black. The specific heat capacity of Novaculite is 0.74 kJ/Kg K and that of Diabase 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
