The marine Jurassic succession of Jaisalmer basin has been classified into three distinct formations namely Jaisalmer, Baisakhi and Bedesar Formations in ascending order of antiquity. These are underlain by non‐marine sequence of Lathi Formation which has been dated as Liassic to Bathonian by Das Gupta (1975) and as Liassic by Lukose (1972). The calcareous

Geography and climate

The area is sandy from one side, other side barren land, one side fertile Khadins are there and one side salt water lake is situated. Digitally processed satellite images have unearthed the hidden course of a major lost river below the sands of the Thar Desert, in the India–Pakistan (Indo-Pak) region. The great Himalayan river of the Vedic period (10 000–8000 BP) is mentioned in ancient Indian literature. It was called the ‘Saraswati’ in India and the ‘Hakra’ in Pakistan and it dried up during 4000–3500 BP. Large numbers of archaeological sites from the Harappan civilization occur along the dry river bed. The mapped course of the river is 4–10 km wide and conforms to the size described in the Rigveda. The newly described course is validated through the drilling of tube wells in the channels and through archaeological, hydrogeological and sedimentary data. An enormous quantity of potable water has been found along these channels. The path of the (main) river course, the likelihood of the river shift and the reasons for its disappearance are discussed. One path traced out as below mentioned- Bahla–Ratund– Mohangarh–Lanela–Dawa–Devran–Giral–Kanod–Gadra road.(A. K. Guptaa, J. R. Sharmab & G.
