Formation

Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

Norite 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 Norite and Diabase Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. 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 Norite vs Diabase information and Norite vs Diabase characteristics in the upcoming sections.

More about Norite and Diabase

Here you can know more about Norite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Diabase consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Diabase is available in dark grey to black colors. Appearance of Norite is Veined and Shiny and that of Diabase is Vesicular. Properties of rock is another aspect for Norite vs Diabase. Hardness of Norite and Diabase is 7. The types of Norite are Ultramafic intrusive 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 Norite and Diabase is black. The specific heat capacity of Norite is 0.52 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.Norite is impact resistant, pressure resistant, wear resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
