Geology 103 (Sedimentology and Stratigraphy)
California State University, Sacramento
Carbonate shelf systems, Modern reefs
Upon completion of this unit students should be able to:
- Describe the physical and oceanographic conditions that favor reef formation.
- Discuss the five main types of carbonate shelves, and give examples of each: rimmed shelf, unrimmed platform, carbonate ramp, isolated platform, epeiric platform.
- Identify the energy levels, facies, and rock or sediment types. that are present in the outer shelf, middle shelf and inner shelf of a carbonate shelf that is protected from wave action.
- Be familiar with the formation and occurrence of a barrier reef, fringing reef, atoll, patch reef and deep water or cold water reef.
- Discuss the difference between a framework reef, a bioherm and a carbonate buildup
Evaluate the physical factors that affect modern reefs Comment on the future of carbonate reefs on planet Earth
