Blackband ironstones are, typically, fossiliferous sapropel-rich (usually with an organic content in excess of 10%) finely laminated sideritic ironstones. Although non-laminated types are known, more frequently they are formed of alternating siderite- and organic-rich laminae. They are found almost exclusively above coal seams in a lacustrine parasequence with mudstone and seat earth deposits ...
