Definition
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

Archaeological Significance
Formation
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

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