Formation
Foidolites 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 Foidolite and Pantellerite
Here you can know more about Foidolite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Pantellerite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene 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 Foidolite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Foidolite is Dull and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Foidolite vs Pantellerite. The hardness of Foidolite is 1.5 and that of Pantellerite is 6-7. The types of Foidolite are Igneous rock 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 Foidolite is white while that of Pantellerite is . The specific heat capacity of Foidolite is 0.79 kJ/Kg K and that of Pantellerite is 0.84 kJ/Kg K.
