Quizplus · Accepted Answer

Limestone is a sedimentary rock that is primarily composed of calcium carbonate, which is often derived from the accumulation of shell fragments from marine organisms. Animal bones and plant debris can also contribute to the composition of limestone, but they are not as common as shell fragments. Fragments of granitic and andesitic rocks are not typically found in limestone.
