Limestone and Migmatite

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

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

All about Limestone and Migmatite Properties

Know all about Limestone and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Migmatite belongs to Metamorphic Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Migmatite is Foliated. Limestone appears Rough and Banded and Migmatite appears Dull, Banded and Foilated. The luster of Limestone is dull to pearly while that of Migmatite is dull to pearly to subvitreous. 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 Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. The commercial uses 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 and that of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
