Oolite. Oolite is one of the most unique-looking varieties of limestone. It looks like many small, round pellets cemented together. These pellets, called ‘ooids’, are formed when calcite precipitates out of water directly onto grains (usually silica) and grow in high-energy environments. Oolitic limestone - Weldon.

In the unbroken examples the oolite just looks like a tiny ...Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface. Limestone wears better than sandstone, is more easily shaped than granite, and weathers from nearly white to a beautiful gray. Oolitic limestone, quarried in Lawrence, Monroe, and Owen counties in Indiana, is a particularly fine building stone.
