Ooids (/ ˈoʊˌɔɪd /, [1] from Ancient Greek ᾠόν (ōión) 'egg stone') [2] are small (commonly ≤2 mm in diameter), spheroidal, "coated" (layered) sedimentary grains, usually composed of calcium …

Oolite or oölite (from Ancient Greek ᾠόν (ōión) ' egg stone ') [1] is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. [2] Strictly, oolites consist of ooids of …

Jul 1, 2024 · Ooids are concentrically-laminated, sedimentary grains produced through successive stages of carbonate precipitation and abrasion that typically form above wave base in tropical …

Mar 1, 2019 · Ooids are spherical or ovoidal carbonate grains (typically <2 mm in diameter) of smooth, well-laminated cortices that accrete around a nucleus, typically a bioclast, peloid, …

Aug 30, 2019 · Ooids, pisoids, oncoids and pelloids comprise the most common non-skeletal component of limestones. The first three are characterized by enveloping laminations that …

Jan 29, 2018 · Here we investigate a rare and beautiful geophysical problem that combines both of these processes; the shape evolution of carbonate particles known as ooids.

Ooids are small rounded accretionary mineralized bodies. They could be called sand grains, but they are no ordinary sand grains. Just like normal sand grains, ooids have a diameter reaching …

Common ooid nuclei are peloids and fragments of Halimeda, red algae, and mollusks. You might find these chapters and articles relevant to this topic. Most Upper Jurassic reservoirs are …

OOIDS are a distinctive type of sand that usually form on the sea floor. After they have been buried under additional sediment, such sand grains can be fused into a solid mass of …

Ooids are spherical-subspherical grains, consisting of one or more regular concentric lamellae around a nucleus, usually a carbonate particle or quartz grain. Sediment composed of ooids is …
