Reconstruction of paleo-hydrology using analyzed clumped isotope ratios in palaeosol carbonates and δ18O of carbonates.
The values are compared with the GNIP observation and model based estimates of meteoric water isotopic composition at varying level (2x, 4X, 8X and 12X) of atmospheric CO2. The vertical error bar denotes the δ18O of precipitation estimates established analyzing number of samples of paleosol carbonates from specific startigraphic horizon as described in the text. A large offset from the model results was noted for the carbonates from Bagra formation, suggesting anomalously excess evaporation during the deposition of these sediments.
