Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
Norite 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 Norite and Pantellerite
Here you can know more about Norite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Pantellerite consists of mineral content and compound content. The mineral content of Norite includes Augite, 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 Norite vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Norite is Veined and Shiny and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Norite vs Pantellerite. The hardness of Norite is 7 and that of Pantellerite is 6-7. The types of Norite are Not Available 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 Norite is black while that of Pantellerite is unknown.
