Formation
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.
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 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. Pantellerite vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pantellerite and Properties of Diabase. Learn more about Pantellerite vs Diabase in the next section. The interior uses of Pantellerite include whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Pantellerite and Diabase, they have various applications in construction industry. The uses of Pantellerite in construction industry include and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Pantellerite and Diabase
Here you can know more about Pantellerite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Diabase consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite 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 Pantellerite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Diabase is available in dark grey to black colors. Appearance of Pantellerite is Layered and Foliated and that of Diabase is Vesicular. Properties of rock is another aspect for Pantellerite vs Diabase. The hardness of Pantellerite is 6-7 and that of Diabase is 7. The types of Pantellerite are Pantelleritic Ignimbrite 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 Pantellerite is while that of Diabase is black. The specific heat capacity of Pantellerite 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.Pantellerite is heat resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
