“…During the Quaternary, the Kangra Basin has witnessed several phases of sediment aggradation in the form of alluvial fans (Sah and Srivastava, 1992;Srivastava et al, 2009). IRSL ages from Srivastava et al (2009) suggest loess deposition between 78-44 ka, which is overlain by fluvial deposits.…”

“…Sample field-code Depth (cm) there even during the LGM (Ray and Srivastava, 2010). Prell and Kutzbach (1987) modeled rainfall over the Indian subcontinent during the LGM and found that precipitation was reduced to~70% of presentday values, yet even that lowered amount is thought to have been enough to mobilize sediment and cause aggradation in the valleys (Srivastava et al, 2008;Ray and Srivastava, 2010).…”

The Tibetan Plateau is regarded as an amplifier and driver of environmental change in adjacent regions because of its extent and high altitude. However, reliable age control for paleoenvironmental information on the plateau is limited. OSL appears to be a valid method to constrain the age of deposits of glacial and fluvial origin, soils and periglacial structures in the Menyuan basin on the northeastern Tibetan Plateau. Dating results show glaciers advanced extensively to the foot of the Qilian mountains at~21 ka, in agreement with the timing of the global Last Glacial Maximum (LGM) recorded in Northern Hemisphere ice cores. Comparison with results from the eastern Tibetan Plateau suggests that the factor controlling glacial advance in both regions was decreased temperature, not monsoon-related precipitation increase. The areas of the Menyuan basin occupied by glacio-fluvial deposits experienced continuous permafrost during the LGM, indicated by large cryoturbation features, interpreted to indicate that the mean annual temperature was ≥7°C lower than at present. Glacio-fluvial systems in the Menyuan basin aggraded and terraces formed during cold periods (penultimate glaciation, LGM, and possibly the Younger Dryas) as a response to increased glacial sediment production and meltwater runoff then.

“…Although various archive-proxy based palaeoclimatic researches through Pleistocene-Holocene transition are available from the Indian Himalaya [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] but the poorly dated profiles obstructs their being most ideal high resolution records except for the Tsokar and Tso Moriri multi-proxy high resolution studies [39][40][41] respectively. Further, precisely dated stalagmite based multi-decadal records are rare through the Late Pleistocene-Holocene transition [42] although δ 18 O precipitation variability during Middle to Late Holocene has been obtained through U/Th dated speleothems [21,22,43,44].…”

Investigated for d 18 O and d 13 C isotopes, mineralogy and growth rate, a 20 cm long and 230Th-dated calcite stalagmite from Kalakot (Jammu and Kashmir Himalaya), has recorded high resolution precipitation variability during the Pleistocene-Holocene transition. At present, the study area is influenced by both the Indian Summer Monsoon (ISM) and Westerlies. The StalAge model indicates that the stalagmite grew between 16.3 ka to 9.5 ka BP under the ideal isotopic equilibrium conditions as revealed by the Hendy test results. The d18 O and d 13 C values range from -5.41 to -8.82% and -7.09 to -10.84% respectively. Although the U/Th chronology is poor due to low Uranium content in the samples resulting in relatively large errors, the first stalagmite inferred precipitation variability reconstructed from NW Indian Himalaya makes this study significant. The near footprints of three global events, e.g., Older Dryas (OD), Allerød period and Younger Drays (YD) can be noticed at ~14.3-13.9, 13.9-12.7 and 12.7-12.2 ka BP. The precipitation strength was weaker during the OD and YD, but was stronger during the Allerød interstadial. By the termination of YD interval, the climate seems fluctuating in the NW Himalaya. There seems variation in commencement, duration and termination of the above mentioned events in different parts of the globe due to latitude location and response time.
