Abstract
The lower reaches of the Sind River, a tributory of the Yamuna, exhibits a thick accumulation of Quaternary alluvium deposited by the ancient river system of the Ganga and the present Sind River. The alluvial sequence comprises the Older Alluvium and the Younger Alluvium which are divisible into three lithostratigraphic units, viz., the Gohad-Mau-Mihona Formation, the Bera (Sijroli) Formation, and the Sind Formation. Six geomorphic units, namely, the Denudational Hill, the Jaswantnagar Surface, the Gohad-Mau-Mihona Surface, the Bera (Sijroli) Surface, the Sind Surface, and the Ravinous Tract are identified in the study area between 270 m and 100 m above MSL. The alluvial surfaces, constituting the fluvial terraces and the recent floodplains, reflect a complex process of aggradation and down cutting by the rivers during the morphotectonic evolution of the basin in Late-Quaternary and Recent period. Evidences of two episodes of neotectonism, which could be genetically related to the Himalayan orogenic movements of Late Pleistocene-Holocene period, are identified in the area of study.
