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.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

The uses of Lamprophyre in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Carbonatite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Lamprophyre and Carbonatite
Here you can know more about Lamprophyre and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Carbonatite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Carbonatite, 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, Carbonatite is available in black, brown, green, grey, pink, white colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Lamprophyre vs Carbonatite. The hardness of Lamprophyre is 5-6 and that of Carbonatite is 3. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Carbonatite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lamprophyre and Carbonatite is white. The specific heat capacity of Lamprophyre is 0.84 kJ/Kg K and that of Carbonatite is 0.51 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 Carbonatite is heat resistant, pressure resistant, water resistant.
