This volume includes the papers presented at the International Symposium on Phanerozoic Ironstones held at the University of Sheffield in April 1987. Some sixty workers from eight nations attended the meeting and its accompanying field excursions. These field excursions visited Ordovician and Jurassic ironstones in North Wales, Yorkshire and Humberside. The symposium represented the starting point for the establishment of the International Geological Correlation Programme Project 277: Phanerozoic Oolitic Ironstones in 1988.
Research into iron-rich sediments is currently enjoying a renewal of involvement, as evidenced by the papers presented in this volume and by the enthusiasm displayed at the meeting. Much of the new interest has been generated by improvements in the technology for the investigation of these rocks and by the advancements in the geochemical background necessary for their interpretation. These influences are clearly to be seen in the following papers. We felt that the time was right to bring together those working in the field to discuss the various lines of research currently being pursued and the many different models for ironstone genesis proposed in recent years. The papers contained herein reflect the current diversity of opinion in the field. The scope of the symposium, and hence of the volume, was deliberately restricted to Phanerozoic examples of iron-rich sediments because Precambrian examples have had extensive recent discussion in other symposia (e.g., Trendall & Morris 1983).
Iron has been produced from Phanerozoic ironstones for several millenia, but, these days, the extensive use of Precambrian ores has now largely replaced
