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

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

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