Oolite - Wikipedia
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 of the replacement of the original texture in limestone.
Oolite - Sedimentary Rocks - Sandatlas
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).

Oolitic limestone. Oolitic limestone is made up of small spheres called ooiliths that are stuck together by lime mud. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor.
Oolitic Limestone - SpringerLink
Nov 11, 2019 · 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.

Oct 21, 2023 · Oolitic Limestone: Oolitic limestone consists of small, spherical, or egg-shaped structures called ooids. It can be quite porous and is often used in architectural applications.
Oolite and coated grains - SpringerLink
Jan 1, 2013 · Oolite is a sedimentary rock, most often limestone, composed of smoothly laminated, spherical to ellipsoidal coated grains that are cemented together (Figure O16). The grain components of oolite are called ooids (or öoids or ooliths), terms derived from the Greek word for fish roe (“oon”), which ooids resemble.
