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
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions

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.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Cataclasite and Lamprophyre Properties
Know all about Cataclasite and Lamprophyre properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite belongs to Metamorphic Rocks while Lamprophyre belongs to Igneous Rocks.Texture of Cataclasite is Clastic whereas that of Lamprophyre is Porphyritic. Cataclasite appears Dull and Banded and Lamprophyre appears Dull, Banded and Foilated. The luster of Cataclasite is vitreous while that of Lamprophyre is subvitreous to dull. Cataclasite is available in brown, green, white, yellow colors whereas Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Lamprophyre are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
