Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

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.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

All about Lamprophyre and Granodiorite Properties
Know all about Lamprophyre and Granodiorite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre and Granodiorite belong to Igneous Rocks.Texture of Lamprophyre is Porphyritic whereas that of Granodiorite is Granular, Phaneritic. Lamprophyre appears Dull, Banded and Foilated and Granodiorite appears Veined or Pebbled. The luster of Lamprophyre is subvitreous to dull while that of Granodiorite is grainy, pearly and vitreous. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Granodiorite is available in black, grey, orange, 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 Granodiorite are curling, gemstone, laboratory bench tops, tombstones.
