Definition
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Pegmatite vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pegmatite and Properties of Suevite. Learn more about Pegmatite vs Suevite in the next section. The interior uses of Pegmatite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Pegmatite and Suevite, 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 Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Pegmatite and Suevite
Here you can know more about Pegmatite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pegmatite and Suevite 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 Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Pegmatite vs Suevite, 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, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Pegmatite is Layered, Banded, Veined and Shiny and that of Suevite is Banded. Properties of rock is another aspect for Pegmatite vs Suevite. The hardness of Pegmatite is 7 and that of Suevite is 5.5. The types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Pegmatite is Not Available and that of Suevite is 0.92 kJ/Kg K. 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 Suevite is heat resistant.
