Cretaceous Carbonate Platforms: An Overview
Cretaceous carbonate platforms are some of the largest and most widespread sedimentary units in the geologic column. They developed throughout the Cretaceous Period in the Tethyan region. Furthermore, they have yielded significant amounts of the world's oil production and contain major reserves (Scott et al., Chapter 2, this volume). Cretaceous platforms contain important information about changes in fauna, depositional facies, diagenesis, and climatic events, and they provide clues to platform growth and demise. Comparison of different carbonate platforms from diverse tectonic and climatic settings provides a unique test to constrain basic controls on carbonate platform evolution, including effects of biotic changes, eustatic sea level fluctuations, variations in tectonic subsidence rates, terrigenous sediment influx, paleoclimates, and long- and short-term accretion and demise of carbonate platforms. This volume is designed to present examples and provide stratigraphic and depositional data on several Cretaceous carbonate platforms around the world for comparative purposes.
Figures & Tables
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.
