Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Archaeological Significance
Formation
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Foidolite and Laterite Properties
Know all about Foidolite and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite belongs to Igneous Rocks while Laterite belongs to Sedimentary Rocks.Texture of Foidolite is Earthy whereas that of Laterite is Earthy, Massive, Porphyritic. Foidolite appears Dull and Laterite appears Rough and Banded. The luster of Foidolite is subvitreous to dull while that of Laterite is dull. Foidolite is available in black, brown, green, grey, pink, white colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
