Lamprophyre vs Shoshonite

Definition

Definition

Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

Formation

Formation

Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Shoshonite 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 Shoshonite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Lamprophyre and Shoshonite Reserves. Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions. Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Lamprophyre vs Shoshonite information and Lamprophyre vs Shoshonite characteristics in the upcoming sections.

Lamprophyre vs Shoshonite 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 Shoshonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lamprophyre and Properties of Shoshonite. Learn more about Lamprophyre vs Shoshonite in the next section. The interior uses of Lamprophyre include Decorative aggregates and Interior decoration whereas the interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Lamprophyre and Shoshonite, 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 Shoshonite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Lamprophyre and Shoshonite

Here you can know more about Lamprophyre and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lamprophyre and Shoshonite consists of mineral content and compound content. The mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Lamprophyre vs Shoshonite, 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, Shoshonite is available in brown- black, dark brown colors. Appearance of Lamprophyre is Dull, Banded and Foilated and that of Shoshonite is Dull. Properties of rock is another aspect for Lamprophyre vs Shoshonite. The hardness of Lamprophyre is 5-6 and that of Shoshonite is 6. The types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Shoshonite are Intermediate volcanic rock. 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 Shoshonite is white to grey. The specific heat capacity of Lamprophyre is 0.84 kJ/Kg K and that of Shoshonite is 0.79 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 Shoshonite is heat resistant, pressure resistant.
