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.

More about Lamprophyre and Lignite

Here you can know more about Lamprophyre and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Lignite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Lignite includes . You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. 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. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Lamprophyre vs Lignite. The hardness of Lamprophyre is 5-6 and that of Lignite is 1. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lamprophyre is white while that of Lignite is black. The specific heat capacity of Lamprophyre is 0.84 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lamprophyre is heat resistant, impact resistant whereas Lignite is heat resistant.
