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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Lamprophyre vs Laterite 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 Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Laterite. Learn more about Lamprophyre vs Laterite in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Lamprophyre and Laterite, 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 Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Lamprophyre and Laterite
Here you can know more about Lamprophyre and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Laterite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Lamprophyre vs Laterite. The hardness of Lamprophyre is 5-6 and that of Laterite is 2. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lamprophyre and Laterite is white. The specific heat capacity of Lamprophyre is 0.84 kJ/Kg K and that of Laterite is 0.92 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 Laterite is heat resistant, pressure resistant.
