Formation

Formation

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Amphibolite vs Lamprophyre 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 Amphibolite and Lamprophyre Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions. 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 Amphibolite vs Lamprophyre information and Amphibolite vs Lamprophyre characteristics in the upcoming sections.

Amphibolite vs Lamprophyre 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. Amphibolite vs Lamprophyre characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Lamprophyre. Learn more about Amphibolite vs Lamprophyre in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Lamprophyre include Decorative aggregates and Interior decoration. Due to some exceptional properties of Amphibolite and Lamprophyre, they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Lamprophyre include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Amphibolite and Lamprophyre

Here you can know more about Amphibolite and Lamprophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Lamprophyre consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite and mineral content of Lamprophyre includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Lamprophyre, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Amphibolite is Foliated and that of Lamprophyre is Dull, Banded and Foilated. Properties of rock is another aspect for Amphibolite vs Lamprophyre. The hardness of Amphibolite is 6-7 and that of Lamprophyre is 5-6. The types of Amphibolite are Hornblendite whereas types of Lamprophyre are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Amphibolite is white to grey while that of Lamprophyre is white. The specific heat capacity of Amphibolite is 0.84 kJ/Kg K and that of Lamprophyre 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.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Lamprophyre is heat resistant, impact resistant.
