Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Lamprophyre vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Serpentinite. Learn more about Lamprophyre vs Serpentinite in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lamprophyre and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Lamprophyre and Serpentinite
Here you can know more about Lamprophyre and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Serpentinite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Lamprophyre vs Serpentinite. The hardness of Lamprophyre is 5-6 and that of Serpentinite is 3-5. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Serpentinite are Jadeitite. 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 Serpentinite is white, greenish white or grey. The specific heat capacity of Lamprophyre is Not Available and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
