5 Formation
5.1 Formation
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.
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.

Pegmatite vs Amphibolite 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 Pegmatite and Amphibolite Reserves. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. 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 Pegmatite vs Amphibolite information and Pegmatite vs Amphibolite characteristics in the upcoming sections.

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

More about Pegmatite and Amphibolite

Here you can know more about Pegmatite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pegmatite and Amphibolite consists of mineral content and compound content. The mineral content of Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Pegmatite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Pegmatite is Layered, Banded, Veined and Shiny and that of Amphibolite is Foliated. Properties of rock is another aspect for Pegmatite vs Amphibolite. The hardness of Pegmatite is 7 and that of Amphibolite is 6-7. The types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite whereas types of Amphibolite are Hornblendite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pegmatite is white while that of Amphibolite is white to grey. The specific heat capacity of Pegmatite is Not Available and that of Amphibolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pegmatite is heat resistant, impact resistant, pressure resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
