Definition

Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Oolite and Conglomerate Properties

Know all about Oolite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Oolite and Conglomerate belong to Sedimentary Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Conglomerate is Clastic. Oolite appears Rounded and Rough and Conglomerate appears Shiny and Rounded. The luster of Oolite is pearly to shiny while that of Conglomerate is dull. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Conglomerate are cemetery markers, in aquifers, tombstones.
