Definition

Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Foidolite and Limestone Properties

Know all about Foidolite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Foidolite is Earthy whereas that of Limestone is Clastic or Non-Clastic. Foidolite appears Dull and Limestone appears Rough and Banded. The luster of Foidolite is subvitreous to dull while that of Limestone is dull to pearly. Foidolite is available in black, brown, green, grey, pink, white colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
