 · Limestone usually starts in the biosphere, gets recycled into the lithosphere or geosphere, moves to the atmosphere then back to the biosphere. Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Lime mud gets buried by overlying sediments over long periods of time and turns into limestone.
