5 Formation
5.1 Formation
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 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 vs Greenschist 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 Diabase and Greenschist Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism. 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 Diabase vs Greenschist information and Diabase vs Greenschist characteristics in the upcoming sections.

Diabase vs Greenschist 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. Diabase vs Greenschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Greenschist. Learn more about Diabase vs Greenschist in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Greenschist include Bathrooms, Countertops, Decorative aggregates, Entryways, Homes and Interior decoration.
