Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Lamprophyre vs Teschenite 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 Teschenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Teschenite. Learn more about Lamprophyre vs Teschenite in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Lamprophyre and Teschenite, 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 Teschenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Lamprophyre and Teschenite
Here you can know more about Lamprophyre and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Teschenite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Lamprophyre vs Teschenite. The hardness of Lamprophyre is 5-6 and that of Teschenite is 7. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Teschenite are Not Available. 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 Teschenite is black. The specific heat capacity of Lamprophyre is Not Available and that of Teschenite is Not Available. 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 Teschenite is impact resistant, pressure resistant, wear resistant.
