Figure 5: Curvature of Modi Khola litholigies


View Original Image at Full Size

Figure 5. These maps show mean, minimum, maximum, range, standard deviation of curvature for each lithology of the Modi Khola valley. Negative curvature represents valley shaped topography and positive curvature represents ridge shaped topography. Visual inspection of changes in these maps reveal differences in curvature statistics between different lithologies and across the range. Each lithologic unit was used as the zone (or region) to calculate curvature statistics within. Refer to the geologic map of the Modi Khola in Martin et al. (2010) to identify lithologic units. MD - Macchapucchare Detachment, DD — Deorali Detachment, FRM II - FRM I — Formation II - Formation I lithologic contact, BF— Bhanuwa Fault, MCT — Main Central thrust, RF — Romi Fault, TF — Tobro Fault, GT — Ghandruk thrust, RT — Ramgarh thrust. Geographic coordinate system: WGS 1984 UTM Zone 44N. Projection: Transverse Mercator.
