Annual Report 2006 of the Rupelian/Chattian Boundary Stratotype Working Group

A revised version of the paper on “Integrated stratigraphy of the Oligocene pelagic sequence in the Umbria-Marche basin (Northeastern Apennines, Italy): A potential GSSP for the Rupelian/Chattian boundary” by Coccioni and others, was re-submitted to the Geological Society of America Bulletin in January 2006. This version was returned to the first author at the end of August for a second revision which is presently underway. The new further revised manuscript will be re-submitted to the GSA Bulletin by next November in the hope it will be accepted for publication.
This long revision process delaied considerably the preparation of the formal proposal designating the Monte Cagnero (MCA) section, out of the three sections studied, as GSSP for the Rupelian/Chattian boundary.
