Formation

Formation

Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
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.

Greenschist 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 Greenschist and Diabase Reserves. Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism. 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 Greenschist vs Diabase information and Greenschist vs Diabase characteristics in the upcoming sections.

Greenschist 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. Greenschist vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Greenschist and Properties of Diabase. Learn more about Greenschist vs Diabase in the next section. The interior uses of Greenschist include Bathrooms, Countertops, Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Greenschist and Diabase, they have various applications in construction industry. The uses of Greenschist in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Cutting tool, For road aggregate, Roadstone and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Greenschist and Diabase

Here you can know more about Greenschist and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Greenschist and Diabase consists of mineral content and compound content. The mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc 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 Greenschist vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Greenschist is available in dark greenish - grey, green colors whereas, Diabase is available in dark grey to black colors. Appearance of Greenschist is Layered and Shiny and that of Diabase is Vesicular. Properties of rock is another aspect for Greenschist vs Diabase. The hardness of Greenschist is 3.5-4 and that of Diabase is 7. The types of Greenschist 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 Greenschist is white while that of Diabase is black. The specific heat capacity of Greenschist is 0.84 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.Greenschist is impact resistant, pressure resistant, water resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
