Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
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 Mudstone and Travertine Properties
Know all about Mudstone and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone and Travertine belong to Sedimentary Rocks.Texture of Mudstone is Clastic whereas that of Travertine is Banded. Mudstone appears Rough and Dull and Travertine appears Fibrous. The luster of Mudstone is dull while that of Travertine is dull to pearly. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Mudstone are creating artwork, pottery and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
