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.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Foidolite and Benmoreite Properties
Know all about Foidolite and Benmoreite properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite and Benmoreite belong to Igneous Rocks.Texture of Foidolite is Earthy whereas that of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular. Foidolite appears Dull and Benmoreite appears Rough and Dull. The luster of Foidolite is subvitreous to dull while that of Benmoreite is earthy. Foidolite is available in black, brown, colourless, green, grey, pink, white colors whereas Benmoreite is available in black, brown, light to dark grey colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Benmoreite are commemorative tablets, creating artwork, curling.
