Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
  
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
  
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Oolite and Limestone Properties
Know all about Oolite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Oolite and Limestone belong to Sedimentary Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Limestone is Clastic or Non-Clastic. Oolite appears Rounded and Rough and Limestone appears Rough and Banded. The luster of Oolite is pearly to shiny while that of Limestone is dull to pearly. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow 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 Oolite are creating artwork, jewelry, 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.
