Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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.

All about Laterite and Mugearite Properties
Know all about Laterite and Mugearite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Mugearite belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Mugearite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Laterite appears Rough and Banded and Mugearite appears Dull and Soft. The luster of Laterite is dull while that of Mugearite is not available. Laterite is available in brown, buff, red colors whereas Mugearite is available in black, brown, light to dark grey colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Mugearite are creating artwork.
