Location: From 9° to 11 ° 30' south latitude and 35° 30' to 37° west longitude, Sergipe, northeastern Brazil
Geologic time interval: Middle Cretaceous, late Aptian–early Coniacian (Epicheloniceras sp-Diadochoceras sp.–Eodouvilleiceras sp. zone to the Solgerites armatus–Prionocycloceras lenti zone)

Cretaceous Carbonate Platforms
With the large amount of information from Cretaceous basins available for comparative studies in the early 1990s, it seemed appropriate and timely to make available these regional studies on carbonate platforms, aiming at a convenient and objective presentation in a standard format. This volume represents the result of that effort. It brings together 32 well-documented data sets on carbonate platforms from 17 countries, which represent a significant part of the spectrum of Cretaceous carbonate platforms in different geologic provinces and tectonic settings. Two introductory articles summarize some of the main aspects of the Cretaceous period, carbonate platforms, and economic resources, and review each case study. The objectives of this book are to document styles of formation, growth, and development of Cretaceous carbonate platforms and to compare platform geometries, dimensions, and styles of similar platforms but different tectonic-sedimentary settings.
