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).

The type of silica cement observed in a sandstone seemingly is related to the presence or absence of impurities in the sand. Chert cement or finely divided silica is associated with sandstone containing clay (as in the upper siltstone of the Dakota formation in Ford and Hodgeman counties) or iron oxide (as in some samples from McPherson and Kearny counties).
