ironstone is a rock containing (at least) fifteen percent iron.
Ironstone sedimentary rock forms when iron-rich minerals oxidize in a marine or lacustrine environment, producing iron oxide deposits. Over time, these deposits accumulate and harden into ironstone through compaction and cementation processes. Water plays a crucial role in transporting the iron minerals and aiding in the formation of ironstone.
