Archaeological Significance
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.
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

All about Oolite and Oil shale Properties
Know all about Oolite and Oil shale properties here. All properties of rocks are important as they define the type of rock and its application. Oolite and Oil shale belong to Sedimentary Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Oil shale is Splintery. Oolite appears Rounded and Rough and Oil shale appears Muddy. The luster of Oolite is pearly to shiny while that of Oil shale is dull. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Oil shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Oil shale are an oil and gas reservoir.
