Information concerning the glacio-eustatic controls on Quaternary cool-water carbonates is dominated by data contained within the Holocene to Recent marine shelf record. However, this information represents only part of a full eustatic cycle. Much of the data comes from Southern Ocean-based biofacies studies associated with seafloor sediments. Geophysical studies provide further information on earlier Quaternary seafloor deposits and yield valuable data on sediment geometries; however, these works yield little direct information that can be applied to carbonates at outcrop scale. In contrast, Quaternary cool-water carbonates in the Mediterranean region offer outcrops with continuous exposure along which facies changes are readily accessible for study. In southern Italy and Sicily in particular, post-depositional uplift permits outcrop-based studies of large tracts of Quaternary microtidal cool-water carbonates, containing complete interglacial eustatic cycles. This study examines the carbonates associated with the Emilian sub-stage of the early Quaternary Calabrian Stage.

Cool-Water Carbonates: Depositional Systems and Palaeoenvironmental Controls
During the past decade, work on cool water carbonates has expanded to become a mainstream research area. Studies on modern and Quaternary deposits will continue to be important; however, there is increasing momentum towards unravelling sediment processes, biota-sediment interactions and diagenetic products in Cenozoic and older cool-water carbonates.
Many contributions in this book document Cenozoic and Quaternary carbonates from landlocked (microtidal) water-bodies. These carbonates display important differences in biota and fabric distributions when compared with world ocean examples. Consequently, the scientific community is now better placed to reinterpret pre-Tertiary carbonates where there is a suspicion that they have developed under microtidal conditions. Some papers in the book provide new approaches to interpreting environmental change within macrotidal regimes and others lay firm foundations for future cool-water carbonate diagenetic research
The aim of the book is to illustrate recent international contributions to cool-water carbonates research, with an emphasis on Neogene and Recent case studies. Contributions are divided into three sections: microtidal carbonates from the Mediterranean realm; macrotidal examples from New Zealand, Australia and Mexico; and early diagenetic fabrics.
