Formation
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.
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

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