Abstract:

The landscape in fact, is the manifestation of folds, faults, joints, height of rocks, their constitution, and resistance to previous processes operating on them. It is necessary to present the aerial distribution of the various rock groups or litho-tectonic settings and to indicate the role of these rock formations relating to the study of geomorphological problems. Proper understanding and assessment of the geomorphological features requires the study of the geology of the entire area as well as the knowledge its history. The rocks are much older than the geomorphological forms developed upon them. This paper presents the faulting, folding, and igneous institutions, sedimentations, etc. have attributed complexity to the geology of the Sona River basin lying in the southern part of the Chotanagpur upland. The vestiges of several geological occurrences have been completely wiped out by denudational processes. The sequential orogenic cycles are closing at 3200, 2700 and 850 mya, in the Singhbhum and it adjoining regions in eastern India, is strikingly similar to those in another Precambrian shield area of the world. The sediments derived through those processes were arranged in horizontal layers. It was in the Archean era itself that these sedimentary layers were folded into tangled masses of hill ranges by regional metamorphism.
