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.

All about Foidolite and Granophyre Properties
Know all about Foidolite and Granophyre properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite and Granophyre belong to Igneous Rocks.Texture of Foidolite is Earthy whereas that of Granophyre is Granophyric. Foidolite appears Dull and Granophyre appears Veined or Pebbled. The luster of Foidolite is subvitreous to dull while that of Granophyre is dull to grainy with sporadic parts pearly and vitreous. Foidolite is available in black, brown, green, grey, pink, white colors whereas Granophyre is available in black, grey, orange, pink, white colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Granophyre are curling, gemstone, laboratory bench tops, tombstones.
