Iron-rich sedimentary rocks Wikipedia

Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).

IRON AND STEEL chemguide

Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.
