Delve into the fascinating world of coastal peatlands through a 52-minute video lecture that examines case studies from the Late Cretaceous and Paleocene periods. Explore the dynamic nature of these systems, which exist at the intersection of shallow marine and fluvial depositional environments, and learn about their significant role in accumulating plant matter. Discover the seemingly paradoxical occurrence of low sulfur and low ash peats forming near marine influences and active clastic depositional environments. Examine how the rock record reveals the presence of these coal types throughout geological history. Gain insights from two specific examples of preserved coastal peatlands: one from the Late Cretaceous in the USA and another from the Paleocene in Australia. Enhance your understanding of these complex geological systems and their importance in Earth's history.
