Sedimentary Rocks and the Rock Cycle

Grain size is a good indicator of the energy or force required to move a grain of a given size. Large sediments such as gravel, cobbles, and boulders require more energy to move than smaller sand, silt, and clay sized sediments. Grain size is also an indicator of the distance or length of time the sediments may have traveled.

Oolitic Limestone - Assignment Point

Oolites are often used in the home aquarium industry because their small grain size (0.2 to 1.22 mm) is ideal for shallow static beds and bottom covering of up to 1″ in depth. Also known as “oolitic” sand, the sugar-sized round grains of this sand pass easily through the gills of gobies and other sand-sifting organisms.

Grainstone - Wikipedia

Under the Dunham classification (Dunham, 1962) system of limestones, a grainstone is defined as a grain-supported carbonate rock that contains less than 1% mud-grade material. This definition has recently been clarified as a carbonate-dominated rock that does not contain any carbonate mud and where less than 10% of the components are larger than 2 mm. ...

Limestone - University of Kansas

Oolitic limestone - Oolites are small rounded particles or grains, so named because they look like fish eggs. Oolites commonly are formed by layers of material (usually calcite), that have been deposited around some tiny particle such as a sand grain or fossil fragment and are rolled back and forth in quiet waters.
