Application of Aerial Photographs and Landsat Imagery for Geological Mapping Around Chandrapur (Maharashtra)

Abstract

Linear quartzite ridges were established in the NE part of the imagery, from the aerial photointerpretation and later ground check. The extreme eastern part of the imagery has distinct evidences of faulting within the folded strata. Other structural features such as fault planes and doubly plunging synclinal features are also established. Three major formations such as granites, quartzites, and granite gneisses and schists could be delineated on the photogeological map along with the dolerite dykes of later origin. Numerous water bodies with N-S and NNW-SSE alignment are suggestive of the presence of hidden basement faults. Also the Wainganga river's older courses could be clearly marked, besides establishing the structurally controlled flow of Penganga, Wardha and Wainganga rivers. Dissimilar rock units are differentiated from the interpretation of colour composites.
