The interpretation of past events in earth history on a supra-regional scale requires precisely dated and well correlated stratigraphic schemes. Only synchronous events and evolutionary trends can be interpreted in a global context. Events of local or regional character have therefore to be accurately correlated with time-equivalent shifts in other areas in order to be interpreted in a wider context. One of the problems of inter-basin correlation based on biostratigraphy lies in floral and faunal provincialism of the relevant index fossils. In order to overcome such limitations, chemostratigraphy can be used as a stratigraphic tool independent of biostratigraphy. Nevertheless, chemostratigraphy has also its own setbacks like biofractionation processes and diagenetic overprint, among others. So, what can we trust? During the last decade, both chemo- and biostratigraphy have evolved rapidly, resulting in new and more refined dating schemes. Ideally both approaches should be applied jointly, thereby supplying a reliable multi proxy scheme. With new data coming in, new problems arose. We therefore aim in this session at discussing the current status of this integrated multi proxy approach. We are encouraging presentations which contribute by presenting case studies of complementary data sets, but also examples of antagonistic results. Our aim is to bring together scientists from various chemo – and biostratigraphic backgrounds interested in this topic throughout the Phanerozoic eon.
