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.

The volume has been organized into four major sections following a very necessary Introduction to the terminology of ironstones. The Geochemical and Mineralogical Framework, so important in the understanding of the formation of ironstones, sets the scene. The broader Stratigraphic Patterns are considered in a series of authoritative papers on a global and regional scale. Intriguing and complex aspects of the Fabrics of irons tones from the submicroscopic to the mesoscopic are then covered, and the volume is completed by a series of Case Studies from various locations in the world.
