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.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

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