Formation

Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

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

All about Syenite and Limestone Properties

Know all about Syenite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Syenite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Syenite is Earthy whereas that of Limestone is Clastic or Non-Clastic. Syenite appears Banded and Foilated and Limestone appears Rough and Banded. The luster of Syenite is subvitreous to dull while that of Limestone is dull to pearly. Syenite is available in brown, buff, cream, green, grey, pink, white 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 Syenite are cemetery markers, creating artwork 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.
