Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Migmatite vs Limestone 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. Migmatite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Migmatite and Properties of Limestone. Learn more about Migmatite vs Limestone in the next section. The interior uses of Migmatite include Countertops, Flooring and Kitchens whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Migmatite and Limestone, they have various applications in construction industry. The uses of Migmatite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Migmatite and Limestone
Here you can know more about Migmatite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Limestone consists of mineral content and compound content. The mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black 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. Appearance of Migmatite is Dull, Banded and Foilated and that of Limestone is Rough and Banded. Properties of rock is another aspect for Migmatite vs Limestone. The hardness of Migmatite is 5.5-6.5 and that of Limestone is 3-4. The types of Migmatite are Diatexites and Metatexites whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Migmatite and Limestone is white. The specific heat capacity of Migmatite is Not Available and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Migmatite is heat resistant, pressure resistant whereas Limestone is pressure resistant.
