Palaeoclimate and glaciology

Pollen, C/N ratios and δ13COM from a 1.2 m thick palaeolake deposit at Sangla, Kinnaur, Himachal Pradesh provide records of climatic changes during the past 10,000 years. The C/N ratios together with pollen data indicate high lake level between 10,000 and 4,000 yrs BP. Following this, an increase in δ13C (+ 2‰) indicates stressed climatic conditions, whereby δ13COM attained a value of–23‰, being the maximum for the available record. This event is bracketed between 3500 and 1500 yrs BP. Subsequently, the lake ...
