Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
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 Mugearite and Travertine Properties
Know all about Mugearite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Mugearite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Travertine is Banded. Mugearite appears Dull and Soft and Travertine appears Fibrous. The luster of Mugearite is not available while that of Travertine is dull to pearly. Mugearite is available in black, brown, light to dark grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Mugearite are creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
