oolite

ovoid or spherical crystalline deposit with a concentric or radial structure; most are composed of calcium carbonate, but some are composed of silica, siderite, calcium phosphate, iron silicate, or iron oxide. Oolite diameters range from 0.25 to 2 mm (0.01 to 0.08 inch), with most being in the 0.5- to 1-millimetre range; oolitic bodies with diameters greater than 2 mm are called pisolites.
