Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Available in Lots of Colors and Patterns, Generally rough to touch, Is one of the oldest rock
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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

All about Lamprophyre and Eclogite Properties
Know all about Lamprophyre and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Lamprophyre is Porphyritic whereas that of Eclogite is Earthy. Lamprophyre appears Dull, Banded and Foilated and Eclogite appears Dull, Banded and Foilated. The luster of Lamprophyre and Eclogite is subvitreous to dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Eclogite is available in black, brown, green, grey, pink, white 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 Eclogite are creating artwork, gemstone.
