Kachchh is a tectonically controlled palaeo-rift basin. Correlation of major structural fabrics with sequential growth of minor geomorphic configuration is well understood by applying morphometric parameters in the northern Island Belt region of Kachchh. The present study is an attempt to correlate morphometric studies with field based geomorphic features to find out the active tectonics of the Island Belt Uplift of Kachchh. Morphometric parameters like long profiles, gradient index, mountain front sinuosity etc suggest tectonically active landscape. Two to three distinct knick points and peaks on the long profiles and gradient indexes of key drainage basins are complement with three bedrock terraces and three scarps indicating three episodes of tectonic pulses along the IBF and associated transverse faults during the Quaternary period.
