Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Travertine Properties
Know all about Conglomerate and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Travertine belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Travertine is Banded. Conglomerate appears Shiny and Rounded and Travertine appears Fibrous. The luster of Conglomerate is dull while that of Travertine is dull to pearly. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
