Definition
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals

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

All about Pegmatite and Limestone Properties
Know all about Pegmatite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Pegmatite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Pegmatite is Pegmatitic whereas that of Limestone is Clastic or Non-Clastic. Pegmatite appears Layered, Banded, Veined and Shiny and Limestone appears Rough and Banded. The luster of Pegmatite is grainy, pearly and vitreous while that of Limestone is dull to pearly. Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
