Geomorphic unit | Image elements | Landform characteristics (Ground observation) | Area in sq. km. |
Structural hills | Dark red tone coarse texture irregular shape | Linear to arcuate hills, dissected, granitic rocks mostly dendritic drainage, jointed ridges, average height 300 m. strong to very steep slopes | 260.234177 |
Denudational hills | Dull red tone, coarse texture irregular shape | Weathered granite, dendritic drainage, moderate to steep slopes, sparse vegetation | 127.2507 |
Residual hills | Dark grey tone, coarse texture shape and size-irregular and rounded | Erosional surfaces, isolated mounds which have undergone the process of denudation, Steep slopes, radial drainage act as runoff zones | 131.443052 |
Pediments | Light red to red tone, moderate to fine texture | Gentle to moderate slopes, devoid of vegetation with various depths of weathering material, shallow sediment covers rocky and gravely surfaces, dendritic to sub-dendritic drainage, mostly vegetated or cultivated lying at foot hills | 512.468246 |
Shallow weathered pediplains | Green-bluish mixed tone moderate to fine texture | These units are characterized by the presence of relatively thicker weathered material. The thickness of the weathered material is (up to 5 m. These hydrogeomorphic units are developed mostly upon Mayurbhanj Granite | 793.759105 |
Intermontane valley | Green-bluish mixed tone moderate to fine texture | A linear or curvilinear depression valley within the hills, filled with colluvial deposits of IOG sediments | 0.981388 |
Plateau | Dark red tone coarse texture irregular shape | Table land shaped hill with flat surface at the top with sloping sides | 129.419945 |
