5.1 Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.
