Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Foidolite and Talc carbonate Properties
Know all about Foidolite and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Foidolite belongs to Igneous Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Foidolite is Earthy whereas that of Talc carbonate is Very Soft. Foidolite appears Dull and Talc carbonate appears Soft. The luster of Foidolite is subvitreous to dull while that of Talc carbonate is pearly. Foidolite and Talc carbonate are available in black, brown, green, grey, pink, white colors. The commercial uses of Foidolite are cemetery markers, commemorative tablets, creating artwork and that of Talc carbonate are manufacturing of baby powder.
