Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Features
Is one of the oldest rock, Typically speckled black and white.
Stalactites and stalagmites are formed from this rock, Surfaces are often shiny, Very fine grained rock
Archaeological Significance

-
Colosseum in Rome, Italy, Sacré Coeur in Paris, France, Trevi Fountain in Rome, Italy
Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.
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 Tonalite and Travertine Properties
Know all about Tonalite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Tonalite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Tonalite is Phaneritic whereas that of Travertine is Banded. Tonalite appears Banded and Foilated and Travertine appears Fibrous. The luster of Tonalite is subvitreous to dull while that of Travertine is dull to pearly. Tonalite is available in black, brown, light to dark grey, white colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Tonalite are cemetery markers, creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
