Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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 Laterite and Diabase Properties
Know all about Laterite and Diabase properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Diabase belongs to Igneous Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Diabase is Aphanitic, Granular. Laterite appears Rough and Banded and Diabase appears Vesicular. The luster of Laterite is dull while that of Diabase is . Laterite is available in brown, buff, red colors whereas Diabase is available in dark grey to black colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
