All about Migmatite and Limestone Properties

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