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.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

All about Travertine and Diabase Properties
Know all about Travertine and Diabase properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Diabase belongs to Igneous Rocks.Texture of Travertine is Banded whereas that of Diabase is Aphanitic, Granular. Travertine appears Fibrous and Diabase appears Vesicular. The luster of Travertine is dull to pearly while that of Diabase is . Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Diabase is available in dark grey to black colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
