Geologic and Tectonic Framework and its Landforms Evolution of the East Midnapore Coastal Stretch, West Bengal, India
Abstract: The East Midnapore coastal stretch of West Bengal represents a dynamic geomorphic and tectonic environment shaped during the late Quaternary, particularly over the last ~6000 years following Holocene sea-level fluctuations. The region displays different coastal landforms, including sandy beaches, dune complexes, and tidal flats formed through marine transgression?regression cycles and fluvial sediment supply, primarily from the Subarnarekha and associated river systems. Geo-dynamically, the area lies within the Bengal Basin, a tectonically active zone influenced by the convergence of the Indian, Eurasian, and Burmese plates. Geological analysis discloses multiple depositional phases from the Cretaceous to Holocene, with significant contributions from fluvial, lagoonal, and marine environments. Subsurface stratigraphy indicates alternating sedimentary sequences reflecting environmental shifts. Tectonic lineaments, predominantly oriented NE?SW, further highlight structural control over basin evolution. This study provides an integrated understanding of geomorphic development, sedimentation processes, and tectonic influences shaping the East Midnapore coastal zone.
