Definition

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

All about Limestone and Adakite Properties

Know all about Limestone and Adakite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Adakite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Adakite is Porphyritic. Limestone appears Rough and Banded and Adakite appears Dull and Soft. The luster of Limestone is dull to pearly while that of Adakite is grainy, pearly and vitreous. 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 Adakite is available in black, brown, light to dark grey 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 Adakite are commemorative tablets, pottery, used in aquariums.
