The Thar Desert and its antiquity

For long, widely divergent views (based on isolated pieces of historical evidence or broad geological evolution of the subcontinent, notably the rise of the Himalayas in mid-late Miocene), had prevailed regarding origin and antiquity of the Thar Desert. Studies of the past few decades have since provided a wealth of new information on landform styles, evolutionary processes and palaeoclimate history with chronometric and isotopic constraints. Salt lakes, dunes and calcrete-bearing alluvial aggradations have been the focus of interest. This review synthesizes the multidisciplinary work to present the state of the Thar during the Quaternary period.
