Evaluation of Tectonics along Western Extension of Gavilgarh Fault Zone, Central India using Geomorphic Indices

Abstract

ABSTRACT The study examines various morphometric parameters and geomorphic indices within sub-basins along the Western extension of the Gavilgarh Fault zone. The combined analysis of these factors serves as a crucial tool for assessing tectonic activity in the region, showing strong correlations with structural discontinuities and geomorphological anomalies. The study area, located Southeast of Jalgaon, Maharashtra, demonstrates recent tectonic activity, especially in sub-basins P1 to P6. Fluvial patterns within the region reflect tectonic influences, as evidenced by various geomorphic indices. The study categorizes sub-basins into different levels of tectonic activity based on these Geomorphic indices and field observations. Additionally, slope analysis, satellite imagery, and field data reveal the presence of drainage anomalies and tectonic indicators such as V-shaped valleys, waterfalls, knick points, and more. The Relative Index of Active Tectonics further classifies subbasins according to their tectonic activity levels, shedding light on the complex interplay of geomorphic and tectonic features in the Western extension of the Gavilgarh Fault zone. Overall, this study enhances understanding of the geological processes and tectonic forces shaping the region.
