Formation

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.

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.

Granulite 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 Granulite and Diabase Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite vs Diabase information and Granulite vs Diabase characteristics in the upcoming sections.

More about Granulite and Diabase

Here you can know more about Granulite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Diabase consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Diabase is available in dark grey to black colors. Appearance of Granulite is Veined or Pebbled and that of Diabase is Vesicular. Properties of rock is another aspect for Granulite vs Diabase. The hardness of Granulite is 6-7 and that of Diabase is 7. The types of Granulite are Metamorphic 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 Granulite is white while that of Diabase is black. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
