What Would You Do With A Limestone Rock? - Mini Me Geology Blog
Limestone is a fine-grained sedimentary rock that forms when calcium carbonate precipitates in a quiet ocean environment such as deep, calm water. You cannot see individual grains with the naked eye in a fine-grained rock. Limestone is often white, pink, red, gray or black. Fossils are common in limestone because the calm ocean allows the calcium carbonate to precipitate around a dead plant or animal part without significantly disturbing the specimen. There are many varieties of limestone.
