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

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.
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.

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