Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

Limestone vs Pegmatite 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. Limestone vs Pegmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Pegmatite. Learn more about Limestone vs Pegmatite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Pegmatite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Limestone and Pegmatite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Pegmatite include As dimension stone, Building houses or walls, Construction aggregate, For road aggregate, Landscaping.
More about Limestone and Pegmatite
Here you can know more about Limestone and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Pegmatite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Pegmatite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Limestone is Rough and Banded and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Limestone vs Pegmatite. The hardness of Limestone is 3-4 and that of Pegmatite is 7. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Pegmatite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Pegmatite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Pegmatite is heat resistant, impact resistant, pressure resistant.
