Oolite

The limestone that makes up these cave formations is known as "travertine" and is a chemical sedimentary rock. A rock known as "tufa" is a limestone formed by evaporation at a hot spring, lake shore, or other area.

Oolitic limestone is made up of small spheres called ooiliths that are stuck together by lime mud. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor.

Oolitic Limestone Sedimentary Rock

Oolitic Limestone is a white, pink, red, gray or black sedimentary rock composed of mostly calcite oolites. Oolites form when layers of calcite are deposited around a sand grain or fossil piece and then rolled around in relatively calm water, making them round.

Oolite

Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.
