Oolite - Sedimentary Rocks

Oolite 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 Limestone Sedimentary Rock - Mini Me Geology

Oolitic Limestone is a white, pink, red, gray or black sedimentary rock composed of mostly calcite oolites. Oolites form when layers of calcite are deposited around a sand grain or fossil piece and then rolled around in relatively calm water, making them round. Due to the calcite

Oolitic Limestone - Assignment Point

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 seafloor. Oolite or oölite (egg stone) is a sedimentary rock formed from ooids, spherical grains composed of concentric layers.

Oolite - Wikipedia

Oolite or oölite (egg stone) is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. The name derives from the Ancient Greek word ᾠόν for egg. 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.

oolitic limestone – iDesignWiki

Limestone is a sedimentary rock consisting of 50% of calcium carbonate (CaCO3) in the mineral calcite form. Its origins can be traced back to either chemical or biochemical processes that occurred in the past ( hundreds of millions of years ago). It usually forms in clear, warm, shallow marine waters from the accumulation of shell, coral, algal, and faecal debris. However, it can also be ...
