Summary:The terminology and classification scheme used in an accompanying paper are expounded. An iron formation is considered to be a stratigraphic unit which consists mostly of Fe- rich chemical sedimentary rock, specifically with >15% Fe; the rock is called ironstone. Iron formations may be classified into six groups on the basis of the sedimentary environment in which they accumulated: shallow-volcanic-platform iron formations (SVOP- IF), metazoan-poor, extensive, chemical-sediment-rich shelf-sea iron formations (MECS-IF), sandy, clayey and oolitic, shallow island-dotted-sea iron formations (SCOS-IF), deep-water iron formations (DWAT-IF), sandy, oolite-poor, shallow-sea iron formations (SOPS-IF) and coal-swamp iron formations (COSP-IF).
