Oolite or oölite (from Ancient Greek ᾠόν (ōión) 'egg stone') is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. Strictly, oolites consist of ooids of diameter 0.25–2 millimetres; rocks composed of ooids larger than 2 mm are called pisolites. The term oolith can refer to … Ver mais 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 and chert ooids are most likely the result … Ver mais Some exemplar oolitic limestone was formed in England during the Jurassic period, and forms the Cotswold Hills, the Isle of Portland with its famous Portland Stone, and part of the North York Moors.

WebThe succession in the Tizra Formation shows an excellent exposure of a small open marine platform where alternating microbial boundstones (buildups) and oolitic/bioclastic grainstone (shoals) and packstone facies tempestites occur repetitively for a sort interval only 0.55 Myr, an scenario unknown in the geological record. The relatively small extent …
WebThe origin of these porous trends is related to the depositional and diagenetic history of upper Smackover carbonates and overlying Buckner evaporites. Shoal water oolitic and peloidal grainstones of the upper Smackover were deposited across basement and salt-related topographic highs. daredevil comic 29Web28 de jun. de 2011 · Oolitic and bioclastic shoals tend to accumulate on topographic highs where energy is high, but the location of these highs may shift over time.
