8 ¹³ C and 8 ¹⁸ O time record and palaeoclimatic implications of the Holocene calcareous tufa from south-eastern Poland and Eastern India (Orissa)

Measurements of 8 ¹⁸ O and 8 ¹³ C in tufa samples dated by ¹⁴ C method have been used to reconstruct climatic changes in Southern and Eastern Poland and in Eastern India (Orissa) for the last ca 13,500 years. Stable isotope time record 8 ¹⁸ O in calcareous tufa profiles can be interpreted as palaeoclimatic record if dependence between oxygen isotope composition and temperature for the specific climatic region is known. Estimated sedimentation temperatures of calcareous tufas from Polish sites indicate the mean year of air temperatures during the last 12,000 years and mean winter and summer temperature for Orissa state, using stable isotope analysis for calcareous tufa from Indian sites. The estimated temperatures have real values, comparable with contemporaneous sedimentation temperature. The characteristic trend of the temperature changes increasing for Poland and decreasing for Orissa, since the beginning of the Holocene till today, can be observed with climatic optimum ca 5000-6000 BP synchronous in both countries.
