Sediment characteristics, floods, and heavy metal pollution recorded inn an overbank core from the lower reaches of the Yangtze River

摘要

Overbank sediments contain abundant information about floods, paleoenvironmental changes, and recent pollution history of a river basin. For the purpose of understanding modern overbank sediments and their environmental significance, this multidisciplinary study sampled a core from the overbank and a short core from the overbank outcrop at Nanjing in the lower reaches of the Yangtze River. The overbank deposit comprises fine-grained discontinuous strata, including silt, sandy silt, silty sand, a
