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

Archaeological Significance
Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
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 Lamprophyre and Cataclasite Properties
Know all about Lamprophyre and Cataclasite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Cataclasite belongs to Metamorphic Rocks.Texture of Lamprophyre is Porphyritic whereas that of Cataclasite is Clastic. Lamprophyre appears Dull, Banded and Foilated and Cataclasite appears Dull and Banded. The luster of Lamprophyre is subvitreous to dull while that of Cataclasite is vitreous. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Cataclasite is available in brown, green, white, yellow colors. The commercial uses 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) and that of Cataclasite are commemorative tablets, creating artwork.
