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.

The uses of Pegmatite in construction industry include As dimension stone, Building houses or walls, Construction aggregate, For road aggregate, Landscaping and that of Marble include As dimension stone.
More about Pegmatite and Marble
Here you can know more about Pegmatite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pegmatite and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Pegmatite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Pegmatite is Layered, Banded, Veined and Shiny and that of Marble is Veined and Shiny. Properties of rock is another aspect for Pegmatite vs Marble. The hardness of Pegmatite is 7 and that of Marble is 3-4. The types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pegmatite and Marble is white. The specific heat capacity of Pegmatite is Not Available and that of Marble is 0.88 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 Marble is heat resistant.
