Welcome to the International Geological Congress Field Trip T178 Florida Phosphate Deposits. We hope you will enjoy this excursion in Florida. The trip will visit active phosphate mines in central and northern Florida and a limestone mining operation.
Phosphorites deposited in the southeastern United States during the Miocene have attracted the attention of geologists for many years. Numerous studies have investigated the genesis, diagenesis, stratigraphy, mineralogy and extent of these deposits, however, questions concerning the phosphorites and the associated sediments remain. The interest in the phosphorites has resulted in the development of this field trip and guidebook.
