Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

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.
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.

All about Foidolite and Pantellerite Properties
Know all about Foidolite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite and Pantellerite belong to Igneous Rocks.Texture of Foidolite is Earthy whereas that of Pantellerite is Eutaxitic. Foidolite appears Dull and Pantellerite appears Layered and Foliated. The luster of Foidolite is subvitreous to dull while that of Pantellerite is earthy. Foidolite is available in black, brown, green, grey, pink, white colors whereas Pantellerite is available in dark greenish - grey colors. The commercial uses of Foidolite and Pantellerite are cemetery markers, commemorative tablets, creating artwork.
