Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Etymology
From Greek lampros bright and shining + porphureos purple
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

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.
Lherzolite 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 Lamprophyre and Lherzolite Properties
Know all about Lamprophyre and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Lherzolite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Lherzolite is Grenue. Lamprophyre appears Dull, Banded and Foilated and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Lamprophyre and Lherzolite is subvitreous to dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Lherzolite is available in black, dark greenish - grey, green, pink, purple 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 Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums.
