Abstract
The present scientific pursuit attempts to quantify various geomorphic parameters associated with the Chromite and Nickel ores of Sukinda valley and to establish geomorphic features like land forms, slope, relative relief, drainage pattern, density and frequency, lineaments and erosion surfaces. The present morphologic features of the valley were studied by taking inputs from relevant False Colour Composite, Toposheets and by undertaking ground truth checks. It is observed that both these ores are associated with parallel drainage pattern, which is prevalent in the valley, and are characterised by low drainage density and frequency. However Nickel ore exhibits a higher range in drainage density i.e. from 0.4 to 3.0 km./sq. km. in comparison to Chromite. As regards to erosion surface Cr is found to be associated with 140m and 200m end surfaces while Ni is confined to only 140 m. Though the range of slope varies for both the ore types from 0 to 5 degrees, Cr is reported to be associated mainly with foothills and Ni with valley flats.
