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.

Caveman to Chemist Projects: Lime and Lye

Calcium carbonate is white in color, though impurities may lend color to rocks and minerals. The carbonates are chalky in consistency. In fact, chalk is one variety of limestone, though modern classrooms use chalk made of gypsum (calcium sulfate). Lime (calcium oxide) is produced by heating limestone or seashells (calcium carbonate).

Ground Calcium Carbonate / Limestone

Limestone, which is primarily calcium carbonate, is a sedimentary rock made from the minerals calcite or aragonite.

How do different types of lime compare?

Lime or limestone (calcium carbonate) is a naturally occurring rock that is used to raise the pH of acid soils. The amount of lime required to increase the pH of a soil by one pH unit depends on the buffering capacity of the soil. The buffering capacity is a measure of the soil's ability to resist change in pH.
