Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

All about Lamprophyre and Lignite Properties
Know all about Lamprophyre and Lignite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Lignite belongs to Sedimentary Rocks.Texture of Lamprophyre is Porphyritic whereas that of Lignite is Amorphous, Glassy. Lamprophyre appears Dull, Banded and Foilated and Lignite appears Veined or Pebbled. The luster of Lamprophyre is subvitreous to dull while that of Lignite is dull to vitreous to submetallic. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Lignite is available in black, brown, dark brown, grey, light to dark grey 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 Lignite are electricity generation.
