Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

All about Limestone and Wackestone Properties
Know all about Limestone and Wackestone properties here. All properties of rocks are important as they define the type of rock and its application. Limestone and Wackestone belong to Sedimentary Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Wackestone is Clastic. Limestone appears Rough and Banded and Wackestone appears Rough and Dull. The luster of Limestone is dull to pearly while that of Wackestone is dull. 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 Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow 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 Wackestone are cemetery markers, pottery.
