Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.

All about Lamprophyre and Breccia Properties
Know all about Lamprophyre and Breccia properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Breccia belongs to Sedimentary Rocks.Texture of Lamprophyre is Porphyritic whereas that of Breccia is Brecciated, Clastic. Lamprophyre appears Dull, Banded and Foilated and Breccia appears Layered, Banded, Veined and Shiny. The luster of Lamprophyre is subvitreous to dull while that of Breccia is dull to pearly. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, 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 Breccia are creating artwork, gemstone, jewelry.
