Sedimentary basin screening techniques using remote sensing bathymetry data and ArcGIS for eastern continental margin of India

Remote Sensing bathymetry which scans the sea floor reflects dominant geomorphological features. Understanding depositional processes in a deep water environment can be viewed as an important tool for any exploration. Eastern continental margin of India represents a pericratonic passive margin characterized by various en-echelon faults running parallel to coast line. This study aims to classify the eastern offshore of India into various types based on basin configuration. Major geomorphic attributes like slope, azimuth, and flow accumulations are used to provide the preliminary highlights of quantitative analytical techniques using ArcGIS software with 3D and spatial analyst tool. Using the GEBCO global bathymetry data, the qualitative classification is adopted along eastern offshore India margin based on their morphology. Quantifying dimension and spatial variability on regional scale shall throw light in understanding the basin geology & tectonic process. © 2014 CAFET-INNOVA TECHNICAL SOCIETY.
