Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
  
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
  
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.

All about Appinite and Oolite Properties
Know all about Appinite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Appinite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Appinite is Porphyritic whereas that of Oolite is Clastic or Non-Clastic. Appinite appears Dull, Banded and Foilated and Oolite appears Rounded and Rough. The luster of Appinite is subvitreous to dull while that of Oolite is pearly to shiny. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Appinite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner and that of Oolite are creating artwork, jewelry, used in aquariums.
