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.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Lamprophyre vs Phonolite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Lamprophyre vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Phonolite. Learn more about Lamprophyre vs Phonolite in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Lamprophyre and Phonolite, they have various applications in construction industry. 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 Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.
More about Lamprophyre and Phonolite
Here you can know more about Lamprophyre and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Phonolite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Phonolite, 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, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Lamprophyre vs Phonolite. The hardness of Lamprophyre is 5-6 and that of Phonolite is 5.5-6. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lamprophyre and Phonolite is white. The specific heat capacity of Lamprophyre is 0.84 kJ/Kg K and that of Phonolite is 0.84 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 Phonolite is heat resistant, impact resistant, wear resistant.
