Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

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.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

All about Oolite and Blueschist Properties
Know all about Oolite and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Oolite belongs to Sedimentary Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Blueschist is Foliated. Oolite appears Rounded and Rough and Blueschist appears Dull and Banded. The luster of Oolite is pearly to shiny while that of Blueschist is dull. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
