Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Laterite and Hawaiite Properties
Know all about Laterite and Hawaiite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Hawaiite belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Laterite appears Rough and Banded and Hawaiite appears Dull and Soft. The luster of Laterite is dull while that of Hawaiite is not available. Laterite is available in brown, buff, red colors whereas Hawaiite 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 Hawaiite are creating artwork, sea defence.
