A possible Proto-Penner river course, running in a NNE direction from the elbow of capture near Penna Ahobilarn and joining the river Tungabhadra near Kurnool, in Andhra Pradesh, has been inferred from a Satellite Remote Sensing based geomorphic study. Occurrence of lag-gravel and diamonds, remnant alluvial tracts, anomalous drainage pattern, etc. are cited as evidences. Some potential areas such as remnant alluvial patches along Proto-Penner river course and alluvial plains along adjacent streams and topographic depressions are indicated as possible areas for alluvial diamond exploration. Various geomorphic features occurring in Archaean denudational hill province and Cuddapah structural hill province are delineated.

Abstract


A possible Proto-Penner river course, running in a NNE direction from the elbow of capture near Penna Ahobilarn and joining the river Tungabhadra near Kurnool, in Andhra Pradesh, has been inferred from a Satellite Remote Sensing based geomorphic study. Occurrence of lag-gravel and diamonds, remnant alluvial tracts, anomalous drainage pattern, etc. are cited as evidences. Some potential areas such as remnant alluvial patches along Proto-Penner river course and alluvial plains along adjacent streams and topographic depressions are indicated as possible areas for alluvial diamond exploration. Various geomorphic features occurring in Archaean denudational hill province and Cuddapah structural hill province are delineated.
