Abstract

The Bay of Bengal, the world’s largest alluvial fan has on numerous occasions been researched, studied, and tested. These have led to many papers being written both about its complex geological past, and its impact on the modern world. Drilling cores, temperature measurements, depth measurements, the content of sediment deposition, and dating of sediments are just some of the few things that have been published about the Bay of Bengal. With all this information available, this project aims to consolidate it all into a comprehensive overview and analyze the data available as a whole. This was done with the hope of developing a better understanding of the Bay of Bengal, it’s numerous complexities and dynamic birth in the late Jurassic.

To better understand the tectonic, lithologic, magmatic, and climatic evolution of the Bay of Bengal, in this study, the definition of Bay of Bengal includes the geographic Bay of Bengal, the Andaman Sea, and the Northern tip of the Indian Ocean (Latitude: 77.5°E to 100.00°E; Longitude: 5.00°N to 22.5°N). We believe the inclusion of such nearby regions should be beneficial, as they lend a larger perspective on the area under study. In this regard, it is important to note some areas of particular interest like 85°E or 90°E ridge and/or regions with negative gravity anomalies. Lack of consolidated analysis of published information have warranted the authors to attempt to explain the Bay of Bengal’s evolution, sediment accumulation, distribution, and it's tectono-climatic impact on the modern world.
