Definition
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Pegmatite and Marble Properties
Know all about Pegmatite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Pegmatite belongs to Igneous Rocks while Marble belongs to Metamorphic Rocks.Texture of Pegmatite is Pegmatitic whereas that of Marble is Granular. Pegmatite appears Layered, Banded, Veined and Shiny and Marble appears Veined and Shiny. The luster of Pegmatite is grainy, pearly and vitreous while that of Marble is dull to pearly to subvitreous. Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors whereas Marble is available in black, blue, brown, grey, pink, white colors. The commercial uses of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz and that of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
