Definition
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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 Minette and Travertine Properties
Know all about Minette and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Minette belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Minette is Porphyritic whereas that of Travertine is Banded. Minette appears Dull, Banded and Foilated and Travertine appears Fibrous. The luster of Minette is subvitreous to dull while that of Travertine is dull to pearly. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
