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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Travertine and Jasperoid Properties
Know all about Travertine and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Travertine and Jasperoid belong to Sedimentary Rocks.Texture of Travertine is Banded whereas that of Jasperoid is Earthy. Travertine appears Fibrous and Jasperoid appears Glassy or Pearly. The luster of Travertine is dull to pearly while that of Jasperoid is vitreous and pearly. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
