limestones
Cave-forming sedimentary rocks
Limestones is the plural of limestone, a sedite rock composed mainly of calcium carbonate.
Different limestones vary in texture, color, and fossil content: The limestones of Indiana have been quarried for building stone since the 1800s.
Geologists distinguish among limestones by their formation—some from ancient seabeds, others from coral reefs or accumulated shells.
