Ooids are most commonly composed of calcium carbonate (calcite or aragonite), but can be composed of phosphate, clays, chert, dolomite or iron minerals, including hematite. Dolomitic …

Oölite, 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 …

An oolite is a sedimentary rock made of ooids (= ooliths), which are approximately spherical, concretionary grains, typically of calcium carbonate, but may be of iron oxides, clays, apatite, …

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 …

Oolite is a type of sedimentary rock, usually limestone, made up of ooids cemented together. An ooid is a small spherical grain that forms when a particle of sand or other nucleus is coated …

An even-textured limestone composed almost wholly of relatively uniform calcareous oolith s (ooid s), with virtually no interstitial material. It is locally an important oil reservoir (such as the …

Oolite is a type of shallow-water sediment composed of evenly coated grains that typically form near the palaeo-equator, within around 30° north and south latitude. It serves as a valuable …

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. What is Oolite? In this section, we will …
