Holocene and Pleistocene Sea-Level Fluctuations, Coastal Erosion Patterns, and Sediment Deposition in Tectonically Active Continental Margins: Insights from Geochronological and Geophysical Data

Abstract

The study of sea-level fluctuations in the Holocene and Pleistocene epochs provides crucial insights into the dynamic interplay between tectonics, climate change, and coastal geomorphology. Tectonically active continental margins exhibit distinct erosion and sedimentation patterns, influenced by eustatic and isostatic adjustments. This paper synthesizes recent geochronological and geophysical research to analyze how coastal systems have responded to past sea-level changes. We examine sediment deposition records, erosional landforms, and stratigraphic evidence to reconstruct paleo-shoreline dynamics. By integrating radiocarbon dating, optically stimulated luminescence (OSL), seismic profiles, and sediment core analysis, this study highlights the complex interrelation between tectonic activity and sea-level variations. The findings contribute to understanding future coastal changes in response to anthropogenic climate change and seismic events.
