Coastal lagoons as archives of event deposits, Belize, Caribbean Sea
Final Report Abstract
Five principal sedimentary facies may be distinguished in coastal environments of Belize, including mud, sand, peat, shell concentrations, and soil. Facies boundaries indicate retrogradation during the Holocene sea-level rise. Facies distribution is characterized by strong heterogeneity. Eighteen sedimentary events were detected that presumably represent storm landfalls. They include shell concentrations, landward thinning sand beds including hiatus, and corals within brackish lagoon sediments (overwash). Comparison with existing local and regional storm records reveals both correlations and discrepancies. Likewise, it is difficult to detect the influence of climate variation and the land-use of the Maya civilization on the sedimentary successions investigated.
