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 diameter 0.25–2 millimetres; rocks composed of ooids larger than 2 mm are called pisolites. The term oolith can refer to oolite or individual ooids.

鲕状灰岩（oolitic limestone）又称鲕粒灰岩，是一种以鲕粒为主要组分的石灰岩，它是一种良好的储油岩。 它是兼具化学和机械成因的石灰岩，形成于碳酸钙处于过饱和状态的海、湖波浪活动地带或潮汐通道水流活动地带。

Oolitic may refer to: Oolite, a sedimentary rock consisting of ooids; Oolitic, Indiana, a town whose name came from the underlying limestone; Oolitic aragonite sand, which is formed naturally, and used extensively in reef aquariums

Oolitic is a town in Indian Creek and Shawswick townships, Lawrence County, Indiana, United States. The population was 1,184 at the 2010 census.

2019年11月11日 · Oolitic limestone is also called oolite, and it is a limestone primarily composed of ooids. Based on the characteristics of the internal ooid structure, oolitic limestones can be divided into normal oolitic limestone, thin crust oolitic limestone, pseudo-oolitic limestone, allochemical oolitic limestone and negative oolitic limestone.

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 are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.

oolitic，英语单词，主要用作形容词，作形容词时译为“像鲕粒岩的；鲕粒岩的”。 [1] oolitic texture 鲕状结构 ; 由球形或椭球形颗粒组成. oolitic beach 鲕粒滩 ; 鲕滩. oolitic chert 鲕状燧石. oolitic delta 鲕粒三角洲. oolitic facies 鲕石相. oolitic shoal 鲕粒浅滩 ; 鲕滩. Oolitic phosphate 鲕状磷减矿石. oolitic formation 鲕状岩层. oolitic dolomite 鲕状白云岩 ; 鲕粒白云岩 [1]

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 phosphate, iron silicate, or iron oxide.

2021年4月27日 · In this article we will discuss the formation of ooids, and how to recognize oolitic limestone in the geological record. An ooid consists of a nucleus (a fragment of shell, a grain of sand, or whatever) around which layers of minerals are deposited to …

（oolitic dolomite）又称鲕粒 白云岩 ，是一种具鲕状结构的白云岩。 鲕粒具有核心及泥晶白云石的同心纹包壳， 胶结物 为亮晶白云石。 按鲕粒的大小可分为鲕粒白云岩、豆粒白云岩。
