Ironstone - an overview ScienceDirect Topics
An ironstone (76) is a sedimentary rock that contains more than 15% iron, which may be present as variable proportions of iron-bearing minerals such as goethite, siderite, and berthierine. Sedimentary ironstones may be hard and calcareous and contain quartz grains, ooliths, pebbles, and a wide variety of macrofossils.

iron processing - Ores Britannica
iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3),

Banded iron formation (BIF) is both the most easily identifiable of all sedimentary rocks and the one whose origin is most enigmatic. Its flamboyant mesoscale banding is defined by planar variations in the proportions of the two main mineral components – quartz and iron oxides – each of which forms about half of the mass of the rock.
