Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
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.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

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