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.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

All about Foidolite and Travertine Properties
Know all about Foidolite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Foidolite is Earthy whereas that of Travertine is Banded. Foidolite appears Dull and Travertine appears Fibrous. The luster of Foidolite is subvitreous to dull while that of Travertine is dull to pearly. Foidolite is available in black, brown, green, grey, pink, white colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
