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.
Pantellerite 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.

More about Diabase and Pantellerite
Here you can know more about Diabase and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Pantellerite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Diabase is Vesicular and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Diabase vs Pantellerite. The hardness of Diabase is 7 and that of Pantellerite is 6-7. The types of Diabase are Dolerite whereas types of Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diabase is black while that of Pantellerite is .
