Vedic Sarasvati river network in the late quaternary period from Manasarovar to Dwaraka: perceived through satellite remote sensing by JR Sharma and Bidyut Bhadra, 22 Feb. 2014 (RRSC, Jodhpur, ISRO)
GEOCHRONOLOGICAL EVENTS OF SARASWATI
DRAINAGE EVOLUTION
Sediments analysis and Optical Stimulated Luminance (OSL)
dating of sand (quartz), Saini et al. (2009) suggested a much
older palaeochannels (~26000 to 28000 BP) than the
Saraswati palaeochannels (2900 to 5900 BP).
Thermo Luminescence (TL) and Optically Stimulated
Luminescence (OSL) dating of sands, Singvi and Kar (2004)
interpreted that major aeolian activities took place with
reduced fluvial activity during 10,000 - 18,000 BP.
Isotopic analysis (H3, O18 and C14) of groundwater samples
along the palaeochannels in Jaisalmer district of Rajasthan
by BARC, Mumbai indicates that age of trapped groundwater
varies from 1340 to 18880 BP (Rao and Kulkarni, 1997; Nair
et al., 1999).
Recently, groundwater samples were analysed by Reddy et
al. (2011) in Jaisalmer district shows
(a) Groundwater of deeper aquifer > 40,000 years
(b) Groundwater in medium aquifer = 9000 to 17,000 years.
Based on foraminifera study, Nigam (2012) advocates that
(a) Lowering of sea level in 7,000-10,000 & 3,000-4,000
years which causes dissociation of Lothal dockyard.
(b) Rise in sea level in 4,000-7,000 & 1,500-3,500 years
which causes submergence of Neolithic settlement in Gulf of
Khambat and Dwaraka in Gulf of Kachchh.
Himalayan drainage in northwest India was existing more
than 40,000 years ago i.e. before the Saraswati civilization.
Vedic Saraswati River was in full majesty during 6,000-8,000
years.
The entire course of Vedic Saraswati River has been
delineated using latest satellite images and validated with
archaeological, drilling and hydrogeological data.
Radiometric ages of river sediments suggests that the age of
Saraswati River (older palaeochannels) may be as old as
28,000 years and flourished during 8000 to 5000 years ago
(younger palaeochannels).
Age of trapped groundwater in the palaeochannels in
Rajasthan shows contemporary age of Saraswati (1340-8910
BP) and as old as 18800BP.
Present day perennial sources of Sutlej and Yamuna/Tons
rivers have been considered as part of Vedic Saraswati River.
Saraswati River network might have been in existence as old
as 28,000 years BP and ceased to be a dry channel during
3792 years BP.
